It turns out cyclists actually should roll through stop signs. Here’s why
When it comes to greening up our transportation systems and reducing the massive carbon footprint left by our daily commutes, there’s a much better solution than trying to get everyone into an electric car. Encouraging increased cycling, whether on electric bikes or good old-fashioned acoustic bikes, has the biggest impact on reduced emissions and the health and well-being of our society. But with safety at the top of the list of concerns for those switching to a two-wheeled commute, more studies are showing that the best way to protect cyclists at the most dangerous point on their rides is to simply let them blow through stop signs in what is commonly known as an “Idaho stop”.
The Idaho stop gets its name from the state that first enacted it into law back in the 1980s. In an Idaho stop, cyclists are permitted to treat stop signs as yield signs, meaning they slow down and look for traffic before continuing through, no full stop required. In many states, the Idaho stop goes further, not just letting cyclists treat stop signs as yield signs but also treating red lights as stop signs.
There are few things more frustrating to anti-cyclist drivers than seeing a bike rider roll through a stop sign or red light (perhaps seeing them zip past traffic by using the bike lane could be one of them?), but studies are now showing that using an Idaho stop is actually safer than requiring cyclists to come to a full stop at stop signs.
As Alvin Holbrook pointed out in Velo, a recent study by the University of Oregon that put cyclists and drivers in over a dozen “live interaction” four-way intersection scenarios revealed results that may surprise some drivers.
The study found that cyclists preferred the Idaho stop method (which is pretty obvious for a vehicle that works largely by maintaining momentum), but also that when drivers received an education about the rolling stop sign law for cyclists, they approached intersections slower than before and created fewer dangerous scenarios for the cyclists.
Alvin explained, “The main takeaway from the study is that a rolling stop law allowed people biking to do an action they preferred in treating a stop sign as a yield. And once drivers were educated, intersection interactions between people biking and driving were no more dangerous than before introducing the law.”
In other words, safety increased instead of decreasing when an Idaho stop was permitted and when drivers were informed of the law.
That’s just one example, but many studies have confirmed the result that Idaho stops, or rolling stop laws, either increase the safety of road users or have no impact (i.e. are no more dangerous to cyclists than requiring a full stop).
Alvin also pointed to a study from Delaware, one of eight states in the US that has an Idaho stop law on the books, which found a 23% decrease in car/bike crashes at intersections after the Idaho stop law was enacted.
Another study performed in Tampa Bay, Florida, (a state infamous for its questionable drivers) and commissioned by the Florida Department of Transportation, “found that dangerous street design and motorists are what put cyclists at risk, not cyclist behavior.” That study found a nearly 90% traffic law compliance among cyclists, which might surprise drivers who tend to remember the few cases they witness of cyclists breaking traffic law, then projecting that onto all riders. But as the study shows, cyclists are generally incentivized to follow traffic law more than drivers since the risks of not doing so are higher.
The least flattering study on Idaho stops comes from Illinois, where the researchers found no difference in the proportion of crashes after the Idaho stop law was enacted. However, they did find that the severity of those crashes decreased. The result was that cyclists were able to move around more efficiently without increasing the rate of crashes and while decreasing serious crashes.
Even the National Highway and Traffic Safety Administration (NHTSA) highlights the fact that “there is no evidence showing bicyclist stop-as-yield laws have increased bike conflicts with other bikes or pedestrians.”
So why is it safer for cyclists to blow through stop signs or continue through a red light after stopping?
It likely comes down to a number of factors, but several of them lead back to the same underlying issue: intersections are the most dangerous location for cyclists since such intersections are designed for cars, not bikes. When stopped at an intersection, cyclists often disappear from the view of car drivers, blending into the background while drivers instinctively look for other cars. A moving bike is more visible to drivers due to millions of years of evolutionary pressure adapting humans to spot movement.
Rolling through stop signs also means cyclists ultimately spend less time in the most dangerous location for them, quickly moving out of intersections and back to the relative safety of bike lanes on straightaways.
And as studies show, cyclists generally don’t blow through stop signs in a dangerous fashion. They’re incentivized to slow down and check for traffic out of sheer self-preservation. They don’t have a 5,000 lb steel cocoon to protect them the way drivers do. This is despite there being a decent chance that the reader’s confirmation bias would argue differently, as it is easy to remember the last time we all saw a cyclist do something dangerous and forget the dozens of cyclists riding safely that we conveniently ignore every day.
But as Alvin points out, “The bottom line is every person on a bicycle has more to lose — and a greater incentive to yield — when entering an intersection than a driver does. A collision between a car and someone walking and biking will always be tilted against the person outside of the car.
Streets are safer when there is a common understanding of what to expect from everyone. Streets are safer when car drivers aren’t able to use stereotypes of cyclists breaking laws to threaten and harass them. And of course, streets are safer when people are biking.”
It’s an exciting week for grid resiliency-lovers in California, as Governor Gavin Newsom followed up his earlier smart grid law and signed another law this week which may require bidirectional charging on EVs in the future – though the law has no hard timeline attached, so it may be a while before we see this happen.
Bidirectional charging refers to the capability of electric vehicles to not just take electricity from the grid to charge, but to output electricity in various forms, whether this be vehicle-to-load (plugging in devices, like the 1.8kW capability on the Kia Niro EV), vehicle-to-home (like Ford’s “Intelligent Backup Power” system), or vehicle-to-grid (like the Nissan Leaf is capable of).
While these applications may seem like a party trick, widespread use of bidirectional charging could lead to huge benefits for efficiency, grid resiliency, and enable much greater penetration of renewable electricity generation.
Most electric grids don’t really have trouble meeting the regular everyday needs of electricity consumers, it’s when big spikes happen that things get difficult. Either on a hot day when everyone is using air conditioning, or a day when electricity generation is curtailed for some reason or another, that’s when things get difficult.
And as climate change makes temperatures hotter, California’s grid is often overtaxed on the hottest summer days, which are becoming more numerous. Even worse, methane-burning fossil gas peaker plants are the highest-polluting form of electricity California consumes, and these are currently used at peak times in order to deal with high demand.
One solution to this problem is adding energy storage to the grid which can be dispatched when needed, and which can fill up when the grid is oversupplying electricity. This helps to balance out supply and demand of electricity and make everything a little more predictable.
This is why there has been a push for grid-based storage like Tesla megapacks, which represent a large source of rapidly-dispatchable energy storage.
But there’s another source of grid-connected batteries out there which was right under our nose the whole time: electric cars.
EVs, which are mostly connected to the internet anyway, could be used as a distributed energy storage device, and even called upon to help provide electricity when the grid needs it. We already see this happening with Virtual Power Plants based on stationary storage, but if cars had V2G, theoretically cars could contribute in a similar way – both saving the grid, and perhaps making their owners some money along the way via arbitrage (buying electricity when its cheap and selling it when its expensive).
The problem is, not many automakers have included V2G capabilities in their cars, and in the cars that do have it, not many manufacturers have made V2G-capable equipment, and the ones who have built it haven’t seen that many customers who are interested in spending the extra money to upgrade their electrical systems with V2G-capable equipment.
So there needs to be something to jumpstart all of that, and California thinks it might just have the thing.
New CA law might require bidirectional charging… eventually.
The idea started in 2023 when state Senator Nancy Skinner introduced a bill which would require EVs to have bidirectional charging by 2027.
As this bill made its way through the legislative process, it got watered down from that ambitious timeline. So the current form of the bill, which is now called SB 59, took away that timeline and instead gave the California Energy Commission (CEC) the go-ahead to issue a requirement whenever they see it fit.
The bill directs the CEC, the California Air Resources Board, and the California Public Utilities Commission to examine the use cases of bidirectional charging and give them the power to require specific weight classes of EVs to be bidirectional-capable if a compelling use case exists.
The state already estimates that integrating EVs into the grid could save $1 billion in costs annually, so there’s definitely a use case there, but the question is the cost and immediacy of building those vehicles into the grid.
The reason this can’t be done immediately is that cars take time to design, and while adding bidirectional charging to an EV isn’t the most difficult process, it also only really becomes useful with a whole ecosystem of services around the vehicle.
Even Tesla, which for years has touted itself a tech/energy company and sold powerwalls, inverters, solar panels and so on, is still only gradually trickling its bidirectional Powershare feature out onto its vehicles.
And that ecosystem has been a bit of a hard sell so far. It’s all well and good to tell someone they can make $500/year by selling energy to the grid, but then you have to convince them to buy a more expensive charging unit and keep their car plugged in all the time, with someone else managing its energy storage. Some consumers might push back against that, so part of CEC’s job is to wait to pull the trigger until it becomes apparent that people are actually interested in the end-user use case for V2G – otherwise, no sense in requiring a feature that nobody is going to use.
Electrek’s Take
Given all of these influences, we wouldn’t expect CA to require bidirectional charging any time soon. But it still gives the state a powerful trigger to pull if other efforts, like the recently-signed smart grid law, turn out not to be enough as California works to, grow, clean up, and make its grid more affordable all at the same time.
But having the force of law behind it could turn V2G into less of a parlor trick and more into something that actually makes a difference the way us EV nerds have been dreaming of for decades now (true story: Electrek once turned down Margot Robbie for an interview and instead talked to some engineers about V2G for an hour).
So, telling manufacturers that California may start mandating bidirectional charging soon means that those manufacturers will perhaps start taking V2G more seriously, particularly given the size and influence of CA’s car market. Even if the CEC doesn’t make it a requirement, the threat of it eventually becoming one means that EV-makers will probably start getting ready for it regardless.
There’s no real point to a single person discharging their car into the grid, but when millions of cars are involved, you could work to flatten out the famous “duck curve,” which describes the imbalance between electricity supply and demand. We hear a lot about “intermittency” as the problem with wind and solar, and grid storage as the solution to that, so being able to immediately switch on gigawatt-hours worth of installed storage capacity would certainly help to solve that problem. And we hope this law helps us get just a little closer to that potential future.

Japanese equipment giant Komatsu dropped its new, 320-ton Power Agnostic 930E mining truck at MinsExpo trade show in Las Vegas, calling it a future-ready solution that can run on diesel, hydrogen, or pure electric power.
Komatsu continues to develop alternative engine technology with the release of its first commercial rigid-frame dump truck with a “power agnostic” platform for running on diesel, hydrogen, or even battery electric power.
That’s because the platform is designed around the concept of a modular powertrain. The design not only gives the Komatsu assembly line an easy way to build diesel, BEV, and hydrogen fuel cell rigid haulers on the same line, but also enables customers to upgrade from diesel to battery electric or hydrogen down the road, if and when whatever logistical obstacles that are preventing them from running an electric or hydrogen solution today are overcome.
“This platform enables mining companies to start with conventional diesel engines and gradually transition to cleaner energy sources as needed, including utilization of trolley assist for diesel or as one of the future dynamic charging solutions for battery trucks to reduce fuel consumption and emissions,” reads Komatsu’s press material. “Whether adopting battery technology, hydrogen fuel cell technology or a combination of energy systems, the Power Agnostic 930E provides the infrastructure and adaptability necessary to meet evolving sustainability goals.”
Potential customers got a sneak peek at the concept truck, which they were apparently allowed to test at Komatsu’s Arizona proving grounds ahead of MineExpo (I wasn’t invited). The first pre-production Power Agnostic 930E prototype will make its way to Sweden in the coming months, where it will be put to work alongside other electric Komatsu machines in Boliden’s Aitik copper mine, one of the largest such operations on the European continent.
Electrek’s Take
Converting gas and diesel-fueled cars to electric at scale is a concept that’s fraught with problems. Far too many to list here, in fact. But heavy equipment?
Everything from excavators to loaders to heavy trucks are already built to be powertrain agnostic, and manufacturers will often offer the same basic vehicle with Cummins, Detroit Diesel, or Volvo Pentapower, so there’s a degree of openness baked into those systems already. Komatsu is just taking that to the next level by adding a modularity of energy storage (fuel tanks, hydrogen cells, or battery packs) to the mix. And, if the project is successful, it could be the first of many.
