To add to that, what about those cities where you have also a good public transport in place like NYC, Lodon, Paris, Berlin and many more? Where it is may be comfortable to use such a service, but also more expansive and more slower (because of traffic jam).

London not only have good public transport and horribly slow/congested roads in the centre. We also have cheap minicabs, Hailo, and at least one "Uber-like" that contracts minicab companies rather than individual drivers. And many of the larger minicab fleets seems fairly similar to Uber in the way they operate as well.

(We also have rickshaws; mostly as a tourist novelty, though)

Doesn't mean they can't do well here too, but certainly a different proposition to one where they only competes against normal taxis.
