Earlier quoted context omitted.
Could you lie when hailing the cab and once inside say they misheard you and say the genuine destination? Not allowed I imagine but pretty hard to enforce that rule? (Genuine question, as a UK reaident I’ve little experience of the US taxi system and have always had excellent service from taxi firms in the UK - as a result I’ve never really understood the problem Uber is solving in the UK)
By law, they have to take you to where you want to go in the five boroughs, plus... Westchester and somewhere else. So the trick is to get into the cab before they figure out that they can speed off before you can grab their number and file a 311 complaint.
Uber solved many of these types of issues democratized access to taxi rides.
