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.
I feel like I won the lottery whenever I have an aggressive driver that knows the city well. It makes me wonder if breaking the law will be the main value proposition of human drivers at some point.
In NY city, I've noticed that taxi drivers will get agressive when we are stuck in traffic. They will start honking, yelling, or changing from one almost stopped lane to another almost stopped lane. I always thought it was theatrical, to show me that they were trying hard, and not just letting the fee increase while they sat stopped in traffic.
