This is a case of phantom braking, which is illegal. People often forget about the most important traffic rule: it is not allowed to cause an unsafe situation.

If you crash into the car in front of you in your lane, the responsibility is yours both morally and legally. The only car which has a valid excuse is the car immediately following the tesla since the tesla inserted itself into its lane then immediately stopped, not allowing it to build a safety distance.

This is not the case in Germany. Unnecessary emergency breaking will have you be at least 50% at fault.

You are putting other people into an emergency situation which is endangering everyone around you.

I was thinking the same. One earlier article about this had a rather inflammatory photo of some twisted-up cars next to an empty baby buggy. But if you watch the video, that’s clearly where some human drivers ploughed straight into the back of the pile-up. The Tesla autopilot failure is really bad, for sure, but those human drivers should be banned for life. There’s no excuse for ramming into a traffic jam because yo…

Good luck maintaining a safe distance on a busy highway when every time you slow to make a space, somebody moves into the space from a different lane.

Traffic jams happen. Do you really expect drivers to just ram into the back of them?

From what I can tell, the car behind the tesla didn't crash into the tesla but stopped before. And so did the car behind that one. It is the cars after that that crashed into each others. While automatic cars doing random things is certainly problematic, clearly the cause of the crash here isn't the tesla, it is other cars not respecting minimum safety distances and not able to stop when there is a traffic jam ahead.

> clearly the cause of the crash here isn't the tesla, it is other cars not respecting minimum safety distances The cause of the crash is the Tesla. You are not allowed to stop on bridges, in tunnels and several other places. The crashes starting with the Nth car and not the 1st is normal. Reaction time of the first car eats into the reaction of the second and so on until there's no more time to stop. Understand that…

Not sure I understand your reasoning. The further you are from the first car, the more warning you get on what's going on, not the other way round. I typically watch not just the car in front of me but 1 or 2 cars ahead. If I see those cars braking, I start breaking. It's the car immediately following the tesla that got the least warning.

That's just further entrenching car dominance. Every mode of transport should be allowed to safely use the roads, and for what it's worth motorcycles are way better for the climate as a mode of individual transport because they weigh maybe 10% of your average modern car.

You'd be surprised. They're woefully unaerodynamic, and emissions standards are pretty lax for them. Something like a CBR300F is about half the emissions of a hybrid and a grom can get lower, but plenty of motorbikes are actually worse than a compact car and getting close to SUV territory.

Still more aerodynamic and fuel efficient than someone riding a full-blown SUV to work solo.

Not everyone drives a Kawasaki Ninja H2 R with 310 hp or whatever the top record is these days. Per German ADAC, the average motorcycle consumes 2-3 liters/100km [1], whereas the average car is at 7-8 liters/100km [2].

You can buy electric scooters nowadays that can drive a lot farther than any car with the same battery. If one was big on emission reduction, one would ban all cars and only allow scooters.

In my opinion 90% of the reason we don’t have more accidents is because people are so predictable. Watch dangerous drivers weave through traffic - it’s only possible because everyone follows spoken and unspoken rules. Randomly stopping is not some “you need to be prepared, it’s your fault” moment.

> Randomly stopping is not some “you need to be prepared, it’s your fault” moment.

Drivers are indeed expected to always be prepared for sudden stops even at the highest speeds.

It’s almost impossible to rear-end another car without being at least partially at fault. The lane change from the Tesla was obviously dangerous, but the first car to collide with it had sufficient warning and time to react. You can see that they did react, but they obviously didn’t expect the Tesla to come to a full stop, which is why the first collision took place. I believe the legal term for this is contributory…

It takes humans up to 5 seconds to even start breaking in the presence of danger. Even at 40 miles per hour your speed is 58 feet per second (or, at 60kmh you speed is 16 meters per second). So it's either "the driver had sufficient warning" or "the lane change from Tesla was dangerous". As you don't expect cars that are dangerously changing to suddenly slow down.

5 seconds?? Lol. Maybe if the driver is 86 years old.

A car switching into an empty lane and then stopping hard even more.

If a human driver did it deliberately as the Tesla did (since it was designed to pull over and stop) then I would consider it a criminal level traffic violation on the part of the stopping car.
