Personally, I really hope they can fix the issues TFL has with them before the repeal period is up. I mean, the convenience and price of Uber is just fucking absurdly ridiculous compared to any other option out there.
Uber feels safer and far nicer than black cabs. Black cabbies are fucking annoying. In my experience they are horrible people, and minicab drivers aren't much better. The anxiety of not having to give an address to black cabbie is fantastic. Uber drivers usually seem happy and nice, although I ascribe that to them seeming new to the job. Black cabbies and minidrivers seems like jaded homocide cops.
For the consumer Uber is just incredible, although, night tube has started and crossrail is about to go into effect, so travelling around London is still getting better, but with Uber getting around is fantastic.
But, I can't deny maybe a company that culturally refuses to see their workers as employees, one that can be as unethical and immoral as Uber, above and beyond norms, perhaps doesn't deserve to operate. Still, it will be much tougher with out Uber in London.
