Personally (and professionally) I think the posters that have gently probed (oo errr missis 😁) the concept of car sharing are fumbling towards a possible future.
The other leg of the dog is autonomous cars that are able to do the boring bit of finding a charger and waiting 2 hours by themselves. Ideally overnight.
When those two ideas coalesce then we'll see nothing but EVs - and fewer of them.
Uber driving will have turned out to be a temporary phenomenon as the world twigs that an empty car meandering around for a charger may as well make a few quid as a taxi on the way. This will spur on a trend of groups of people clubbing together to buy an electric car (or technically "shares" in an electric car) so that they can rake in a share of the profits as all it does all day long is act as a JohnnyCab.
This is pretty much what I put in my work back in 2014. It was on the edges of horizon scanning, but woven from the threads of established technology (a perk of the job being visiting loads of nerd heaven outfits 🤓)
Really, the pandemic came a little too early - if it had waited until around 2028 then it might have turbo charged the concept.
Of course clubs of people putting money into car purchasing (or leasing) means the prices can stay high enough to freeze out the riff raff. But no one really paid attention when I added a "social concerns" section. As a very senior director once said "that's for other people to think about".
Currently the main drag is a flood of "It's all about me" which tends to be easily dealt with. Less easy is the industrial and financial volatility that is extant in the world at the moment. If I were a tinfoil hat wearer, I'd almost believe it was a deliberate move to slow down the onset of the future. Which is a tad paranoid, but has well founded historical precedents.
When I was role playing an objectionist to this, a colleague countered pointing out that we all happily line up to share space with people we wouldn't cross the road for to place ourselves at the mercy of a machine none of them could afford (in fact most airlines can't afford) which is going to practically autonomously fly (FFS !!!!) them hundreds of miles through atmospheric conditions that rival a spin around Hanger Lane for a week of overcharged customer service and bad food.
