I extensively use car sharing services in Europe and it covers almost all of my use cases, the only exception being long distance trips, those are just too expensive when you’re paying by the minute or kilometer at todays prices.
There’s options with fixed parking spots, and services that allow pick up and drop off anywhere.
You tend to structure your life a little different once you don’t own your own car anymore, you start to think twice about little trips you would’ve done otherwise. On the flip side I now have access to 5 different types of cars ranging from small to big (vans) from my phone. It doesn’t even require that much more planning considering it’s reached critical mass around here and there’s a ton of cars available.
The biggest player around is profitable too, so it’s not going away any time too. It’s saved me thousands and spared me from so much hassle surrounding car ownership. I consider myself an enthousiast but I just got a motorcycle for the weekend instead, pennies on the dollar compared to a car.
All in all I notice I’m just happier not being in a car all the time anymore, you might consider it your safe area but it might as well be a golden cage at times.
I understand it’s different once your throw small children in the mix so it might make sense there, but the reality is that a lot of people could do with a lot less car at most points in their life.
