I don’t know why anyone would choose Uber in London.. Requirements to be a cab driver in London are insane... they literally pretty much have to know london streets inside and out to get licensed...
UBER just ignores the law, part of why they have all the issues they have with sexual harassment, because their culture is EFF the law, no matter what it is, we do what we want.
The reason we chose uber was:
One group stranded at night at closed train station in the countryside. Uber arrived in 2 minutes.
Group needed to reach activity site that was a roadside pullover. Uber took us there and came back for us. Geolocation is excellent tool.
Group staying at country camp had cab pickup for london scheduled for 6am pickup. Cab company emailed us at 11pm to cancel. Used uber app in the am and got 3 cars in 3 minutes
Group stranded at Paris Disney in huge crowd looking to board last train back to Paris. Was going to take us back 10 blocks from hotel at 1am. Used app to book uber at 1130pm which sent van for the group. Arrived to pick us in 10 mjnutes. Took us to hotel door.
Did I mention all uber used was credit card on file in my account. No foreign currency required. No tipping. The fare was always displayed before the booking was confirmed.
