My daughter uses Uber to avoid driving her car when she goes out for an evening, so that she can drink, mainly wine, and not worry about drink driving. Surely there are people who use Uber for the same purpose in London England, and would otherwise, but for Uber, drive their own cars to avoid paying for taxis. The taxi monopoly couldn't care less about the increased threat to the public by virtue of an increase  in drink driving. (the British use the term drink driving whilst drunk driving is the term in Canada and the U.S., but one need not be drunk to be a menace on the roads; mere inebriation can do that).
