It's a stupid model to begin with. What brainiac thought people would want to share rides with total strangers? It's pretty obvious it was always going to be a glorified taxi service via an app.
I have a *personal* vehicle for a few reasons, convenience and comfort are the two biggest ones. Know what isn't convenient? Instead of just driving to where I want to go instead you open an app... enter in my destination and look at the route.... then try to identify someone who is on the way but still might have a slight detour... re-plan my route and timing around this detour... accept the ride... get a confirmation it's accepted.... etc. I'm not looking to do all of that. I just want to get in my car and go where I need to go, that's the whole point of having personal transportation.
On the comfort side of things I like not having random strangers next to me. That's one of the benefits compared to using public transportation. Taxi driving is a dangerous profession, turns out picking up random people has risks, who would have thought of that eh? Also no I have to worry about this person, maybe I just want to jam my music but this rando is going to complain about it, maybe they smell because they haven't showered in 2 days.
