In Jan London people were 'extremely unfamiliar' with Uber pool and the 'friendliness' of Londoners is far from the real one of San Franciscan.
I personally ran into situation where a rider joining a pool was so not ready that she commented 'there's a man in the car' and her boy replied with 'kick him out'.
I truly hope the biggest achievement of Uber could be to change Londoners' mindset.
Last time I checked, London was still under UK Government control. So this must have been a blitzkrieg attack. Shows the advantage of having a 100% mobilised army, I suppose.
