Not quite
For the time being the Uber "Interface" does not include:
1. Extra 5 miles detour around Terminal 5 and Terminal 4 if you take a cab from Heathrow and look like a foreigner. Or any other route for that matter
2. Obstruction of public highways when something is not going the Uber way
3. Spending half a day at a taxi rank at an airport chatting with 50 other lazy sods to skin a single mark 10 times the actual fare
And so on.
As long as cabs continue to charge based on time + distance traveled instead of a fixed cost from A-Z based on GPS the issue will stand. Milking Uber will not change a thing as it has a different charge basis which anyone who has been given the 30 mins extra run-around via the scenic route will definitely prefer going forward.
It is time for the Taxi licensing regs to be shredded and updated to the technical realities of today and the journeys to be charged purely on the basis of GPS distance.
