In the centre of town during the day black cabs are often ubiquitous, immediately available, and skilled at getting you the hell out of dodge. Something for which I’m happy to pay a premium.
Anywhere else they can be capricious and scarce. After 11pm this is the case with in fact almost all black cabs anywhere in the city, when a very different type of driver — “borrowing” their license from a friend, card machine with a “sorry not working” post it taped to it, no chat — starts working the night shift. Usually these are more often likely to be rental drivers — during the day it’s owner drivers. The difference between the two classes of driver is, if you will, day and night.
By contrast, the semi robotic Uber will always come, eventually. They’ll drive past you. Go the wrong way to pick you up. Stop on the wrong side of the road and wait for you to cross because they don’t have a tight turning circle. Go the wrong way on your journey. It’s a fact of life that while not all black cab drivers meet the highest professional standards, it’s much rarer to find a good Uber driver.
SF and the Bay Area — I mention them as the root source of Uber’s app and product culture — certainly aren’t a cakewalk to drive around but it’s not a patch on London’s warrens. You can absolutely see that in the navigation skills of those using the big map apps to get around, and those who did The Knowledge. My subjective viewpoint isn’t some romantic notion based on the old ways or traditions either: everyone I know in London has pretty much the same experience.
