In Europe, we have a number of car sharing systems. They all have daily prices around 70-80 euros. As soon as you need a car for two or more days a week, you might as well lease it. Leasing is cheap, compared to the car sharing prices.
I think it has to do with the fact that a lot of the cost of the car is depreciation, which is highly dependent on the mileage driven. Which goes up if you share a car. Plus a shared car needs a host of care takers; app builders, help desk people, car cleaners, etc.
Everyone's betting big on cloud cars, but in fact they're expensive compared to the mass produced item that's called a car.
Two data points which might support this:
1. Consolidation. Drive Now and Car2Go (two big players) are merging.
2. ‘Traditional’ car hire can be way cheaper - we recently had a decent car for (an almost unbelievable) ~€10/day while on holiday. Now I know that we might be comparing apples with oranges here, with the car sharing companies already including features which you pay extra for with the traditional car hire, and of course there are differences in convenience... but that’s still a huge price delta.
I lived in a Drive Now city and used them a few times a month when I thought "I'm too lazy to walk to the subway and wait, and then walk home from the subway/it's too late and the subway is 15 minutes wait", without owning my own car. It would cost maybe 5 Euro to drive home.

When you can lease a car for 200 EUR per month, it does not make sense to use these services for daily use.
Of course if you need a car for 2 days every week that doesn't quite work, and you're better off owning one.
But many people living in cities don't really need a car (can't find a reference right now, but I think less than half of Paris residents own a car).
Basically, your car is an extension of your home. And you are, rightfully, not inclined to share your home with strangers!
Not for me. One aspect I appreciate a lot of owning a car is that I KNOW it's available for me whenever I need it, as soon as I need it.
There was this weekend when my old car was in the shop and I had to go clean up my old rental apartment before I handed over the keys. Since I had to get cleaning stuff there and carry some leftover stuff from there back, I decided to take a taxi. The distance one-way was about 4 km.
I spent an hour going between like 4-5 different taxi apps, including Uber, trying to get someone to come pick me up. It was such a stupid way to spend my time.
