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.
In what couldn’t have been more on-the-nose timing, a group of local California newspapers published an editorial on Christmas Eve calling for the end of a generous $2,000 voucher program intended to help low-income Californians afford electric bicycles for transportation.
The editorial was provided by the Southern California News Group, a collection of California newspapers owned by the hedge fund Alden Global Capital.
In it, the writers air a number of grievances against the program, which recently closed its first round of applications intended to provide around 1,500 e-bike vouchers of between US $1,750 to $2,000 each. The vouchers can be used to offset the price of electric bicycles and associated gear such as protective equipment, locks, etc.
The first complaint in the op-ed is that the total number of vouchers provided in the first round was relatively small compared to the large size of the California e-bike market. However, instead of suggesting that the budget be increased to help more Californians achieve transportation independence, as we called for recently, the editorial takes the opposite position of suggesting that the program simply be canceled.
Next, the writers bemoan an increase in electric bicycle and electric scooter accidents in recent years, suggesting that this should be weighed against the benefits of helping more Californians afford such vehicles.
However, the argument seems to conveniently overlook the fact that the vast majority of such accidents aren’t caused by e-bike riders, but rather those riders are in fact usually the victims. The actual danger to safety on roads is vehicular traffic, i.e. cars and trucks.
Furthermore, many studies have shown that in crashes caused by e-bike riders, such as when an e-bike rider hits another cyclist or pedestrian, the injuries are on average considerably lighter and more recoverable than in car-related crashes.
If the goal was to protect Californians, then instead of firmly clutching their pearls, perhaps the editorial writers should have urged a reduction in the use of cars and trucks, not a reduction in e-bike vouchers.
The op-ed even goes on to lament the number of children riding electric bicycles in California, though admits further on that children aren’t eligible to receive vouchers as part of California’s e-bike incentive program.
Electrek’s Take
California’s e-bike incentive program is certainly far from perfect. We even discussed many of its shortcomings last week. But the program’s essence is to do a good thing—using public tax money to benefit the public. The solution should be to improve the program, not to remove it. And the simple fact of the matter is that most people who are vehemently against the program are those who don’t directly benefit from it, even if they fail to realize that they will ultimately indirectly benefit.
Electric bicycles are one of the most cost-effective ways to provide transportation independence to marginalized and low-income groups. But it’s more than just that. They’re also the best way to get people out of cars and reduce traffic for everyone. Even ignoring the long-term environmental effects related to reducing the impacts of climate change, e-bikes are uniquely capable of making a larger impact on air quality today by helping to remove sources of emissions from a vehicle’s production all the way through its lifetime use and even to its eventual disposal/recycling. When someone rides an e-bike instead of taking a car, taxi, or bus, everyone’s lungs benefit.
Sure, the California program isn’t perfect. But if a media group owned by a wealthy hedgefund and catering to a well-to-do readership doesn’t like it, then that means it’s probably doing something helpful to people who actually need it. That’s the kind of world I want to live in, at least for as long as it’s still liveable.

Sixthreezero’s wide range of electric bike models includes some fairly out-there models, but the company’s new four-wheeled electric bike really charts a new direction in the industry. Take a look at the new ANYterrain Stabilized 4-wheel Electric Bike.
It’s a mouthful of a name, but the ANYterrain Stabilized 4-wheel Electric Bike hauls more than just a bunch of extra words. The bike is rated to carry up to 350 lb (159 kg), and the 750W motor ensures it has the power to do so. With speeds of up to 20 mph (32 km/h), the quad bike is just as fast as most Class 1 and 2 e-bikes.
But the real game changer here is the design, offering four-wheeled stability that riders can’t get from a conventional three-wheeled trike.
Not only do four wheels provide better stability with a wider footprint, but the steering on the bike uses leaning geometry to take turns more naturally, helping riders feel even more stable.
With 20″ wheels in the rear and 16″ wheels in the front, the quad bike keeps a fairly low center of gravity. All four wheels use 4″ fat tires for better offroad riding and more comfortable shock absorption compared to narrow tires, and the rear wheels even feature a differential to better apply the motor’s power to the ground.
A twist throttle makes it easy to roll on that power, and a D/R switch on the bars lets riders put it in reverse for cases where they need a little help wiggling around in tight spaces. Pedaling backward from a stop can also engage the reverse. At 120 lbs (54 kg), this isn’t the type of bike you can just pick up and move around the garage without a little help so that reverse feature will likely come in handy.
A 48V and 20Ah battery offers 960Wh of capacity, which the company says translates into a range of up to 50 miles (80 km).
The battery is housed under a cargo basket in the rear, though a bench seat can be swapped for the basket, allowing riders to carry a passenger with them.
Electrek’s Take
This certainly won’t be a mass market type of e-bike, but I can see a real use case for neighborhood riding and local errands, especially for folks who don’t feel stable on a bicycle or even a trike.
Despite trikes offering great stability when going straight, some people can feel uncomfortable making turns on a trike, especially at higher speeds, because they can sometimes feel tippy under certain scenarios. This quad bike can still tip if you take a turn sharp enough, but the wider stance combined with the leaning steering means riders will even more stable than on a trike.
And since this will likely be used more by older riders, the reverse is an important feature for letting folks park the bike easily without dismounting and dragging it around.
There could be some legal hurdles in some areas that define “bicycles” as having either two or three wheels, but I’m guessing most cops aren’t jumping at the opportunity to ticket grandma for riding her quad bike on the local rails to trails network.
I love seeing more options like this, and I commend Sixthreezero for providing such interesting options to add to the market.
