> Another one is instant availability for open-ended road trips. It's not feasible to go visit a friend two hours away with the possibility of staying overnight with an Uber. Traditional car rental is for this usage case. Availability isn't quite instant but easy a day or so ahead. Uber doesn't need to cover this usage pattern since there's already an extensive market of supply. Sure, if you go every weekend you'd want to own your own car, but for infrequent such trips, regular car rental supplements an Uber-cetric lifestyle just fine.
