I'm in the North East, so I've never used a Waymo, but I swear the last two or so years of ride share of sucked. I mostly take it to and from the airport, but I have about a 50% likelihood of my Uber drive getting either racist, preachy about religion, or taking a wrong turn that ends up tacking on another ten minutes. Usually those come in sets. I used to really like some pleasant small talk or a silent ride (whatever the driver leaned towards), but it's awful in my city now.
Just a month ago my Lyft driver said that God was telling him that the girl he was seeing was a whore because she said he should seek alcohol counseling.
Like six months ago my Uber driver (out of nowhere) said that the driver next to us on the highway (an Audi driving completely normally) must sell drugs to be able to afford a car that nice. The Audi driver was a black man.
When I'm out of town, that rate feels like it decreases though.
That all said, I'd take a Waymo in a heartbeat.
