I was in SF a few weekend ago and rode both Waymo and normal Lyft style taxi cars. the Waymo was a better experience in every single way. One of the Lyfts i was in drove on the shoulder for a while like it was a lane. The Waymos were just smooth consistent driving. No aggressive driving to get you dumped off so they can get to the next fair.
These vehicles very regularly block traffic because they can’t maneuver in congested areas with the finesse of a human driver.
Aggressive driving isn’t always bad. Sometimes it’s to unblock others waiting behind you so they can get somewhere they need to be.
