That's kind of my point - this won't happen, because Uber is already at rock bottom prices. For me to take it to work is about £10. That can't cover anything about the journey and is clearly heavily subsidised by Uber. That cost isn't going down to £5, it's just not going to happen. Just like when people predict that since flash memory prices keep falling down, you will be able to buy a 1TB pendrive for 5 cents. That's not going to happen because you do have the minimum costs of production and transport that aren't going anywhere even if the chips themselves are free.
And if people aren't taking Uber instead of their own cars for these frankly ridiculous prices then I don't see why they would simply because the cars drive themselves.
>>Different services will compete based in part on the luxuriousness of the interiors and the frequency at which they are cleaned.
The same principle should apply to taxis and it just doesn't. I live in a medium size UK city and every company, every brand, has crappy cars. Only price matters, nothing else and Uber Lux is not an option because you're waiting 40-50 minutes for one, that's just not acceptable.
