Just been in London for a couple of days. Booked two Uber rides during my stay from / to London Kings X. Both vehicles absolutely filthy and one of the drivers said we couldn't go the short cut as it involved going through a congestion charge zone ! Utterly ridiculous so instead we sat in an avoidable traffic jam (through long term road works) on Marylebone Road. Uber seem to have really lost their way and will never use them again.
