> It's not like Tesla slamming into something on a freeway at full speed. To be fair, Tesla is not selling a fully autonomous vehicle, yet, people are treating it like one.
And Tesla had encouraged that perception.

I counted 30 seconds of being stuck behind the unloading van with no way to pass without crossing double yellow. I didn't notice the autonomous green light turn off though. Possibly the algorithm is, if you're stuck then certain rules become flexible. Worth mentioning, 30 seconds would feel like an eternity inside a car.
>> Worth mentioning, 30 seconds would feel like an eternity inside a car. Would it, when the car is driving for you and you're free to putter about with a phone or laptop or book? I always figured that this would be one of the greatest benefits of autonomous vehicles - perhaps the car isn't as aggressive as the human it's driving it would be, or as quick to get "unstuck", but the human won't care too much because the…
Level 1: Driver must be ready to take control at any time. Automated system may include features such as Adaptive Cruise Control (ACC), Parking Assistance with automated steering, and Lane Keeping Assistance (LKA) Type II in any combination.
Level 2: The driver is obliged to detect objects and events and respond if the automated system fails to respond properly. The automated system executes accelerating, braking, and steering. The automated system can deactivate immediately upon takeover by the driver.
Level 3: Within known, limited environments (such as freeways), the driver can safely turn their attention away from driving tasks, but must still be prepared to take control when needed.
Level 4: The automated system can control the vehicle in all but a few environments such as severe weather. The driver must enable the automated system only when it is safe to do so. When enabled, driver attention is not required.
Level 5: Other than setting the destination and starting the system, no human intervention is required. The automatic system can drive to any location where it is legal to drive and make its own decision.

Dumb question: how do these systems distinguish a traffic light? Here in New England at least, there's quite a variety of lights, many different modes (red, yellow, green, flashing red, flashing yellow, no-turn-left red arrow, no-turn-right red arrow, and different light technologies: old-fashioned style, Fresnel lens, slotted shade. Add to this complexity the weather conditions. Suppose the sun is shining straight a…
red, yellow, green, flashing red, flashing yellow, no-turn-left red arrow, no-turn-right red arrow You forgot flashing green, which does actually exist, at least in MA. You treat it like a green light, but it could go yellow and then red if a pedestrian presses the walk button.
Nice. It's annoying that they provide only 10x sped up video. Watching this slowed down is helpful. Notes: * There are frequent steering twitches to the left. This may be associated with passing parked cars. There are similar twitches to the right when in the left lane of a one-way street. * Crosswalk behavior when turning needs some work. The vehicle enters the intersection, then stops in the intersection before the…
Every time ... cars pass it, and dive into its lane (a typical reaction to slow moving vehicles).
Still, nice accomplishment.

Some of these issues sound more like issues with the traffic in SF than with the car. Maybe the cars highlight that issues to us and we can fix it instead of work around it. Bicycle lanes turning into turning lanes leads to accidents and aggression between cars and bikes. Trucks shouldn't be allowed to double park. Maybe self driving cars are like there be dev on the team who points out all the shitty code that you'v…

What is scary is how few drivers in California know about this rule or the reason behind it, which is for the safety of the bicyclists. Near my home there are several intersections with bike lanes, and I estimate that perhaps one driver in 10 enters the bike lane to make the right turn as they are required to. In fact, I sometimes get surprised or even dirty looks from drivers making illegal right turns when I do mov…
When only 10% of drivers apparently know the correct way, the problem is with the system not the drivers. Better signage and more consistent (state to state) rules that make common sense would go a long way. Keeping in mind what is common sense to a biker is many times counter-intuitive to a driver. I hate the unprotected bike lanes on the right - as a driver you simply are not expecting people to be passing you on t…
Intersections are the most frequent place for cyclist/driver collisions, and "right hooks" (where a driver fails to merge or yield and turns right into a cyclist trying to continue straight through an intersection) are the most common kind of intersection collision, so your instinct is spot on. Your perception that there aren't that many fatalities is probably partly because traffic deaths don't get reported on much, and partly because collisions involving turns tend to take place at relatively low speed, so fewer of these collisions are fatal than might be the case under other collision circumstances, as speed of the car is by far the strongest predictor of death in a cyclist/driver collision.

I agree with you, but in order for a car to be truly self-driving, it must be able to handle these situations. Just because they're illegal doesn't mean it won't happen
