I work from home quite often due to childcare. I far prefer being in the office and I find I'm more productive because of the work environment there. However most of my team are in various parts of the world so even if I was in work I'd be on the phone/email/instant chat/screen sharing with them anyway. Working from home is a nice option to have.
It's about getting a balance. I wouldn't want to be 100% home based as I'd go insane, but a couple of days a week in the office and a few days WFH is a good balance to strike.
It just occurred to me; whats to stop a black cab also signing up to Uber and driving for them if the rate exceeds black cab rates?
Presumably the licensing and the agreement to have regulated fares that comes with that. I haven't looked into it too closely though.
