Uber's made some difference for me at the margins. I've never tended to get a rental car if I'm just going from the airport into a city and back. But I did tend to e.g. if I were going to some location around Silicon Valley even if the car were mostly just going to sit in a cheap/free hotel parking lot. It was generally easier and it meant I had a car if I wanted to run out to a store or whatever.

Uber pricing and convenience make me think harder about the equation. If I'm really pretty much just going to a hotel for a few days, it's probably a wash so I may just take the Uber.

I'll still rent if I'm going to also be visiting friends or going for a hike--or taking a longer drive to somewhere that I may not even have cell reception. But definitely less than I used to even pre-COVID. And I imagine that urbanites who default to not driving rent even less.
