It gives a clue that the oncoming car is going straight and the white SUV is yielding. If the oncoming car turns the white SUV is also free to turn.The white SUV comes to a stop, presumably signaling (the video is of such poor quality it is hard to tell).
The SUV does NOT turn, in spite of there being no obvious traffic. This gives a clue.
You release the accelerator to position your foot over the brake. Waymo doesn't need to do that.At this point I have released the accelerator and am in regen before entering the intersection. Who knows what is obscured? At least bleed off a few mph!
It looks to me like braking and steering happened simultaneously, a fraction of a second after the green path started to bend. There is latency in perception (e.g. 33 ms for 30 fps video) then additional latency in planner processing then finally latency in the electro-mechanical steering and brake actuators. With a decent quality YouTube we could go one frame at a time and measure things, but this blurry, jerky Twitter feed is useless.I also think the reaction was surprisingly slow given the superhuman response time that should be available to the Waymo Driver. I don't know why you'd path adjust before you started bleeding a lot of speed. There must be reasons but it seems non-optimal for a human driver response.
