Building a history that you won't assault the driver or puke in their car is actually material to them offering you rides. You might not be someone who would try and rob the Uber driver, but lets admit that such people exist, and that it's in Uber's best interest not to let people like that use their platform.
Not to excuse taxi robbers or taxi drivers raping female passengers, but... somehow humanity seems to have existed with that for decades just fine? What is different between now and back then, maybe other than that we're finally taking women seriously?
I use Lyft 99% of the time (and multiple times a week) because I find it to be more reliable (as well as slightly cheaper) than Uber. It doesn't seem destroyed to me.
Also, some uber drivers, take your ride while literally not being in the car and wasting your time. Anecdotally, I took an uber one time that was less than 20m from me. After 5 minutes not moving I went to check wth was going on. The driver was talking with other uber drivers. His excuse over text? Police was checking some papers. I literally was unable to get any other drivers because they were the most close to me.
