I think there is probably a healthy subset of people on here who take Uber etc. all the time. I, on the other hand, maybe take it a half-dozen times a year (plus some private cars to the airport).
I'd love a really good driver assistive system for my car (ala FSD today) but I likely wouldn't actually get driven around a lot more unless the economics were more compelling than seem likely anytime soon.
For most people the economics won't every work out. Uber/Taxis make sense if you only need them a few times per year. However even if the driver is free, if you are using your car daily as most people do it won't work out.
People who yell "share" forget that most people are driving during rush hour, and so the car will be idle the rest of the day anyway. As such there isn't that much money to save by sharing a car.
In my observation, some cities that have "OK" public transit, people can make-do without cars if they Uber, Zipcar, traditional rentals, walk, and use transit. I also observe that it involves a lot of juggling and probably not regular well-outside-of-town trips.
Absent driving yourself at all, you're going to be very limited most places. Which may be OK for continuing a college lifestyle but mostly doesn't work unless you have a partner who handles the driving.
