Isn't this the same guy who said terrorism is “part and parcel of living in a big city”[1]? Yeah forgive me for trusting Uber more than him. Violent terrorists killing innocents is all fine, attacks have become a monthly affair in London. But oh my! How dare Uber flout our ridiculous anti-people taxi regulations and charge people a reasonable fare?!
Also, quoting the Mayor doesn't prove anything. He has veto power over TFL, he can tell them to do anything. Your argument is just an appeal to authority, in this case an authority with a huge conflict of interest and a proven track record of not giving a fuck about common citizens.
