What it really comes down to is the ratio of cost of living for the driver to the amount they take home after buying gas. If I'm almost broke, want to buy more stuff than I can afford, and know I can get $100 worth of rides for $20 worth of gas in less than 2 days, the decision has already been made. As long as I have close to the same buying power, this will remain true.
It's a delicate balance, though, and when you're competing against people in more dire straits who maybe aren't as good at math, at a certain point it could become unviable.

As a general rule, drivers should devote 20% of their earnings to insurance, maintenance, gas, and repairs. When this is accounted for, the average Uber driver earnings are barely above the poverty line.
If I own a self-driving car that sits in my garage from 8 PM to 8 AM, why not just put it on the Uber network and have it make money while I sleep?
As long as people still own cars, why does Uber ever need to own their own fleet? If anything without the actual pain-in-the-ass of actually having to be a driver, I'd think a lot more people would crowdsource their idle vehicles.
Most people follow similar schedules: they go to work at rush hour, ride with co-workers to lunch around noon and then home during the second rush hour. If you are willing to let your car out 6am to 8pm you got some possibilities - but this is when you need/want your car for your own convenience.
Because when people without cars need cars is correlated with when people with cars are using their cars.
