If you watch the videos that insiders have been posting, it never exceeds the speed limits.

If you watch the videos more carefully, you will notice the people who speed by at 85 MPH later enter the screen again, because that is the nature of freeway traffic.

I predict that a few hundred of these on the road will measurably improve safety and decrease severe congestion by being that one sane driver that defuses stop-and-go catastrophes. In fact I think CHP should just contract with them to pace 101 in waves.

"Waves" are really what we would want them to prevent: https://en.wikipedia.org/wiki/Traffic_wave

The autonomous cars can prevent these waves from forming, which would get people to their destinations faster than speeding.

I was on 101 during evening rush hour, speeding along like everyone. Then I saw brake lights from a Waymo. Later followed by all the surrounding cars. Interesting that it was the first to detect a slowdown.

First to apply brake, not first to detect.

Normal human drivers tend to lift off the gas and only brake when they decide that just lifting won't do.

Don't EVs light up the brake lights when regenerative braking engages?

[macintux]

As best as I can tell, not universally. I'm rather obsessive about watching brake lights around me; my state doesn't have safety inspections, so I try my best to alert other drivers when they have brake lights out.

I've definitely observed Teslas coming to a halt, and the brake lights only kick on at the very end. I don't know how widespread the problem is, but it's very annoying.

Teslas illuminate brake lights based on deceleration (until reaching a stop), which is the desired behavior. I use regen braking aggressively to slow down, and different light behavior would give people seizures or make them brake-light-deaf.

If you're annoyed by the braking lights on a Tesla, it's because you're following too (dangerously) closely.

[jeffbee]

Yes this unfortunately varies by make and model. My Honda pretty much hits the lights whenever the vehicle decelerates. Others can come to a dead halt without the lights.

The omnipresent threat of being splattered by someone who's weaving lanes or distracted by their phone and not expecting to see a vehicle doing 20mph (!!!!) below traffic speed is exactly what I want when I'm in a taxi. /s

If you actually thought adoption would benefit us on it's own rather than seeing it a roundabout way to enforce rules that you want to see enforced without buy in from the public you'd want these cars to behave in a way that makes it easier for them to exist in typical traffic.
