Similar, I've been scammed by a taxi once out of three times, Uber/Lyft never out of dozens. The worst with an Uber I've had was a guy who didn't know you could make multiple stops.
I wouldn't say that Uber or Lyft (or other NEMT rideshares) ever scammed me, but I've had enough shitty experiences and felt burned enough times that their reputation is on-par with classical taxi services IMHO.
On the other hand, Waymo has never scammed me; I've never had a conflict with a shitty Waymo driver; and in fact I'm rather happy to participate in their testing phase and give generous feedback about minor things that could be better after each trip.
