A lot of things complained about are criminal offences so it's not a case of NIMBYism.
Uber should buy/rent land near to Heathrow for their vehicles to wait up if the drivers are not prepared to pay to wait at the airport.
I respect Uber drivers for their industrious outlook but as the son of a London cabbie ( active from 1933 - 1968) I will never use Uber as long as I live and am prepared to pay a little extra for a safe journey.
They are breaking the law. How they solve it is immaterial -but Uber need to solve the problem. (A light-hearted suggestion of a bucket in the cab? It would suffice.)
