Most drivers are not conscious about rolling the gas or keeping it stable and drive by pulsing it on and off to maintain speed because they don’t have the attention, finesse, or both to drive smoothly. Also rolling on the inputs is not something most do. I used to train drivers for racing and not stabbing the gas or brakes is a learned skill that takes some time. Where a person will likely accelerate for too long having to then brake harder, a Waymo smoothes out the curve, preserving energy, which also means less jerk.

Not to mention that in SF you have the hills that add to the math.

Teslas do this by default. They have very strong acceleration, since they were marketed as "sports cars" to people who don't know sports cars, and strong regeneration for efficiency and one-pedal driving.

Depends on the driver, but over the years I’ve gotten a decent number who floor it out of every stop sign/light and don’t adequately modulate speed to match the flow of traffic. With how quickly EVs accelerate I could see that making for a less than pleasant ride.

The worst is Revel, which, in NYC, are ALL teslas/EVs. worst taxi experience of my life was a 1 hr drive to airport in stop and go street light traffic. I appreciated the hustle but deleted the app soon after my gag reflex subsided. they should at least disable regenerative braking or something

Yes, although the deceleration seems to be partly due to regenerative braking. They're driving them like normal ICE cars.

In my limited experience, all taxi drivers just do it all the time for time efficiency. They are paid by km most of the time, makes sense.
