As passenger mobility becomes electric and more technologically advanced, engineers have developed several components to make car travel easier, more efficient, and, most importantly, safer. One of those emerging technologies is LiDAR, which has several benefits for OEMs who integrate it. Hesai Technologies is one of the leading companies helping make that LiDAR-centric transition possible.

Hesai Technology is a global leader in LiDAR solutions

Hesai Technology ($HSAI) is three-dimensional light detection and ranging (LiDAR) specialist with offices all over the globe, including Shanghai, Palo Alto, and Stuttgart.

It currently employs over 1,000 personnel who help research, develop, and manufacture advanced LiDAR technologies for a number of applications, including Advanced Driver Assistance Systems (ADAS) in passenger and commercial vehicles, autonomous driving vehicles, as well as last-mile delivery robots and Automated Guided Vehicles (AGVs).

With over 500 granted patents and another 1000+ pending, Hesai puts a lot of time and effort into its LiDAR research and development, and the result is a growing portfolio of advanced safety sensors that can help pave the way for next-generation vehicles coming to market.

LiDAR remains a viable option for next-gen road safety

As advanced driver assistance systems (ADAS) and autonomous driving applications become more prevalent, the question of whether to use LiDAR sensors, vision cameras, or both is becoming hot topic of debate and an increasingly important one.

Many OEMs have shifted from LiDAR ADAS and self-driving applications to a camera-based vision approach, but environmental factors like lighting and weather conditions can cause confusion.

The automotive and robotics industries are racing against one another to advance from Level 2 autonomous driving (where the driver must keep their eyes on the road and hands on the wheel), to Level 3 and L4 autonomy, where the driver is no longer responsible for driving the vehicle. In these applications, Hesai Technology argues that LiDAR, like its ultra-thin long-range ET25 sensor, can make an effective difference while enhancing safety both on and off the road.

The camera conundrum

Cameras have been integral to the development of autonomous vehicles and ADAS vehicles, providing visual inputs like human eyes, and still exist as a viable option to an extent. They can provide valuable color information and visual cues such as traffic light status and road sign recognition.

Furthermore, opting to integrate only one kind of sensor, i.e., cameras, saves on production costs which can be passed along to consumers. 

However, cameras can struggle in challenging conditions. They rely heavily on lighting in a vehicle’s given environment, and their performance can be significantly affected in low light or direct sunlight scenarios, presenting potential safety hazards.

Furthermore, cameras capture two-dimensional images, making depth perception and accurate distance measurement more challenging. These potential limitations underscore the need for more robust perception technology that can provide more information about what’s truly happening in the surrounding environment.

Hesai LiDAR can help enhance safety

LiDAR, such as the AT512 from Hesai, uses laser pulses to scan the environment in three dimensions in real-time. This enables a vehicle’s onboard computer to understand its surroundings, offering a reliable and effective solution to the limitations presented when using camera technology alone.

Hesai Technology’s LiDAR is unaffected by lighting conditions, ensuring consistent performance day and night, and in various weather conditions, including fog and heavy rain, where cameras can sometimes struggle. This independence from external light sources makes LiDAR an effective tool for self-driving vehicles, ADAS, and robots that require reliable and constant navigation capabilities.

Another advantage of LiDAR is its ability to detect objects with high precision and measure their distances accurately. This capability is crucial for vehicles operating on public roads at high speeds, which need to identify hazards, such as pedestrians, other vehicles, and obstacles, from a distance and react accordingly to avoid accidents.

Companies like Hesai have also made significant advances in how LiDAR can be integrated into vehicles, cost, and data security. For example, Hesai’s new ATX LiDAR can be integrated into headlights for a sleeker, subtle design. Moreover, significant advances in LiDAR technology and how it’s manufactured have made it much more affordable, allowing automotive and robotics manufacturers to incorporate the technology without major cost increases for consumers.

Many people don’t know that as hardware, LiDAR is quite secure as it provides data to the vehicle or robot’s central computer for processing without any ability to store or transmit any data wirelessly because it lacks memory, Wi-Fi, Bluetooth, or cellular transmitters.

It also cannot collect biometric data, such as facial scans, because it’s a sensor, not a camera. Furthermore, the 3D maps LiDAR creates of the world around it are not detailed enough for said images.

Tech stacks that maximize safety

Although as a LiDAR technology developer, Hesai would argue it offers superior capabilities in object detection and environmental mapping, the company admits its sensors are most effective when used in conjunction with camera systems.

Camera technology has laid the groundwork for the development of autonomous systems, but LiDAR can help overcome the inherent limitations of cameras and ensure the unparalleled safety that consumers and regulators demand. Combined with vision cameras, Hesai’s LiDAR sensors, like the automotive-grade ultra-high resolution AT128 for instance, can offer vehicles a one-two punch in failsafe ADAS technology.

Hesai explains that the integration of LiDAR technology has already shown promising results in enhancing safety across various applications. In the automotive industry, LiDAR-equipped vehicles have demonstrated improved obstacle detection and collision avoidance capabilities, significantly reducing the risk of accidents. With LiDAR technology rapidly evolving, its integration into new applications is quickly becoming more widespread.

The future of autonomous driving is not just about leading the charge but doing so with the assurance that every possible measure for safety has been employed. As the industry moves forward, Hesai Technology strongly believes the combined use of LiDAR and camera systems will be pivotal in achieving the highest safety standards.

NHTSA is investigating Waymo robotaxis for passing stopped school bus

NHTSA is investigating Waymo robotaxis for passing stopped school bus

Autonomous taxi company Waymo faced scrutiny last month when a car was caught on video illegally passing a stopped school bus that was letting children off in Atlanta. Now, the National Highway Traffic Safety Administration (NHTSA) is looking into it.

Georgia State Representative Clint Crowe seemed stunned after being presented with video of a Waymo driverless car illegally passing a stopped school bus on Briarcliff Road in Atlanta last month. “I’m a big fan of new technologies and emerging technologies and I think that driverless cars are going to become more prevalent,” he told local NBC news affiliate WBIR. “But we got [sic] to think about how they’re going to comply with the law.”

WBIR | Waymo illegally passes school bus


Crowe co-sponsored Addy’s Law in 2024. The legislation was named after 8-year-old Addy Pierce, who was killed in Henry County after being struck while crossing the street to get to her bus. The law stiffened penalties for illegally passing a stopped school bus, carrying penalties of up to $1,000 in fines and even jail time.

According to Crowe, those rules still apply to autonomous vehicles. “The majority of our traffic laws, the penalty is usually a fine and or driver’s license suspension. These cars don’t have a driver, so they don’t have a driver’s license and so we’re really going to have to rethink who’s the responsible party, who’s going to be responsible for being in control of that vehicle and who’s going to be the operator of that vehicle,” he said.

Crowe believes manufacturers should face stronger consequences when their vehicles break the law, saying the $1,000 fine doesn’t go far enough.

WBIR NEWS

Now, thanks to pressure from social media and politicians like Crowe and Geoirgia State Senator Rick Williams, who helped co-author Addy’s Law, it seems like NHTSA is getting involved.

Prompted by media reports, the US Department of Transportation issued an investigation regarding Waymo’s AV, which states that, “the AV initially stopped, but then drove around the front of the bus by briefly turning right to avoid running into the bus’s right front end, then turning left to pass in front of the bus, and then turning further left and driving down the roadway past the entire left side of the bus. During this maneuver, the Waymo AV passed the bus’s extended crossing control arm near disembarking students (on the bus’s right side) and passed the extended stop arm on the bus’s left side.”

While it remains to be seen how much work NHTSA is actually doing amid the ongoing shutdown of the Federal government, it’s worth noting that, regardless of the outcome, Senator Williams said he plans to introduce new legislation that would hold driverless car companies accountable with higher fines if their vehicles violate traffic laws. If that passes in Georgia, it could set the stage for politicians across the US and even abroad to use similar fins to halt the spread of autonomous taxis in their states.

Driverless cars should be stopped until it can be figured out,” said Williams. “We should not have this on the road. It’s too dangerous for our children.”

You can read NHTSA summary, below.

We’re typically pretty tech- and autonomous-forward here, but as a parent I would absolutely lose my s*** if a Waymo or Robotaxi or whatever else ran over my kid. but I’ve also seen plenty of human drivers blow past a school bus with a knee on the steering wheel and both eyes glued firmly to their phones. Let us know who you’d be more ready to trust with your kids’ lives in the comments.

Lion Electric school bus warranties voided, leaving districts stuck [update]

Lion Electric school bus warranties voided, leaving districts stuck [update]

Nobody ever says “this is business” before doing something nice, and the recently reborn Lion Electric company is keeping that streak alive by doing the unthinkable to cut costs: they’re going to void the warranties on hundreds of electric school buses.

UPDATE 01NOV2025: two Lion Electric buses caught fire, now they’re in more trouble.

This past summer, the fallout from Lion Electric’s dissolution reached a critical mass, and the company’s new owners — the Quebec-based real estate giants Groupe MACH — decided to cancel the warranties on electric school buses sold in the US, leaving many districts with unsafe or broken down buses and no recourse to get their money back while the brand continued to take orders and make money in Canada.

Now, it seems like even the Canadian fleets have some serious safety concerns. School Transportation News and the CBC report that The Quebec Ministry of Education has ordered Lion school bus models be taken out of service immediately after a pair of LionC electric buses caught fire in Montreal, Quebec on Sept 9th, leading to disruptions across the province and a renewed scrutiny of Lion bus safety (Lion360 diesel-powered school buses, which Lion manufactured prior to only producing electric vehicles in 2017, were also affected by the issue).

Lion Bus (the company’s new, official name), has issued an inspection bulletin detailing a four-hour repair, which reads, “We have identified some potential anomalies in a sub-component of the HVAC system that Lion obtains from a third-party supplier … in the interest of safety above all else, we request that Lion bus operators perform the following inspections and modifications: mandatory inspection of several low-voltage electrical connections, replacement of certain electrical connectors, replace fan fuses with less powerful ones, adding a fuse to an HVAC control panel circuit. This inspection and modification procedure must be carried out on all Lion360 (diesel) and LionC 3rd generation and earlier buses (Gen3, Gen2 and Gen1).”

No word yet on whether the issue impacts any of the few Lion Electric buses still on US roads, but remember: Lion Bus wouldn’t help you if it did.

You can read about Lion’s decision to leave US school districts holding the bag on its troubled products in the original July post, below, then let us know how you feel about Groupe MACH’s handling of the situation in the comments section at the bottom of the page.

The warranty story

In a letter issued to exiting Lion Electric customers last week, Deloitte Restructuring announced that the warranties on all Lion vehicles purchased outside of the company’s home Province of Quebec are null and void – leaving dozens of school districts in the lurch with stranded assets that won’t get fixed, and can’t be sold to generate funds for replacements.

“We are working with alternate vendors at the expense of the school district to help keep our electric buses functional and on the road,” explains Dr. Richard Decman, Superintendent of Herscher CUSD No. 2 district in Herscher, Illinois. “Currently, six of our 25 (Lion) electric buses need some type of repair.”

Student Transportation News reports that Lion buses represent fully half of Herscher’s overall fleet of 50 buses, and that the district has received nearly $10 million for the purchase of 25 electric buses and the related charging stations from various state and utility incentive programs.

Herscher isn’t the only district having problems with Lion buses. “All four Lion buses that we own are currently parked and not being used,” Coleen Souza, interim transportation director of Winthrop Public Schools, told Clean Trucking. “Two of them are in need of repairs which would cost us money which we are not willing to invest in because the buses do not run for more than a month before needing more repairs.”

More of the same in Maine, where Yarmouth School Department bought two Lion Electric buses in 2023 with the state covering the costs. According to Superintendent Andrew Dolloff, the buses almost never worked. “We’ve had some sporadic service over the past two years, but as soon as the tech leaves, the buses produce error codes again,” explained Dolloff. ” and “Then the technician quits or is released, and we wait a few months for the next response.”

Dolloff added that Yarmouth’s electric buses did not operate during the 2024-25 school year.

Lion’s new owners are seemingly uninterested in their customers’ plight – which might be easily dismissed if those new owners, Groupe MACH, weren’t also the old owners of Lion Electric.

That’s right, kids. Quebec-based real estate company Groupe MACH, which stepped in to “save” Lion Electric earlier this summer, along with Ontario-based Mirella & Lino Saputo Foundation, bought $90 million of equity in Lion Electric back in 2023. And, while the MACH people may not have been the ones who ultimately made the call about voiding the warranties (that decision was made by the Deloitte bankruptcy team), it is absolutely Group MACH who have, to date, not announced plans to continue to honor those warranties, either.

Make of that what you will.

Liebherr MK120-5.1E electric mobile crane rolls into Bern

Liebherr MK120-5.1E electric mobile crane rolls into Bern

The first-ever Liebherr MK 120-5.1E electric crane in customer hands has rolled into the narrow, historic streets of Bern’s old town at 20 meters tall with a 45 meter reach and (of course) zero emissions, no vibrations, and almost no noise.

Deployed by Swiss construction firm Zaugg AG Rohrbach, the new Liebherr electric mobile crane is working hard placing temporary roofs above operational construction sites. It’s precise work, since the narrow streets of Bern’s historic old town weren’t even built for cars — much less massive, five-axle construction machinery. The prices controls and smooth operation of the electric drive mean the MK120-5.1E’s operators could confidently navigate the narrow streets without causing damage and creating new, unpaid jobs for themselves.

“The all-wheel steering allows us to manoeuvre easily in the narrow alleyways,” explained Stefan Stettler, head of the crane department at Zaugg AG Rohrbach. In reverse gear, the crane worked its way along the historic Rathausgasse to its construction site, past the arcades typical of the old town.

In addition to on-board power, the mobile crane can also be plugged into on-site grid power where available, or any mobile power sources capable of offering a steady 63 AMP output for lifting work. A mobile Liebherr Liduro Power Port LPO 100 was on hand in Bern, made available to Zaugg expressly for this purpose. With the Liduro LPO 100 fully charged, Liebherr says the stored energy is good for two full days of crane work.

“The low-noise and emission-free crane work is naturally pleasant for (Bern’s) residents, tourists and passers-by,” explained Stettler. “Especially as we only extended the crane support on the side facing away from the construction site by 50 per cent, allowing pedestrians and cyclists to pass through at all times.”

The MK120-5.1E electric mobile crane offers 8,000 kg (~17,650 lbs.) of lifting capacity, and all of the crane’s drives and winches are powered by electric motors, eliminating both the need to “warm up” or service oil-based hydraulics. It can be had with either a 98 kWh on-board battery (shown) or a 544 hp Liebherr diesel genset.

Electrek’s Take


From compact wheel loaders to radical two-wheeled dumper concepts to massive battery electric retrofit excavators, Liebherr is absolutely killing it in the heavy equipment electrification race. Their electric equipment offerings are proving that EVs can get even the heaviest jobs done, and save big fleets even bigger money while doing it.
