Taxis and ubers are great if you take mass transit but need a back up. Otherwise, you might always be stuck with your car because you lack confidence that you will always be able to take the bus or metro.
Huh, I think this is actually a case where uber's model is a net good rather than just extractive.
There's still congestion to deal with, but a bunch of people whose main work has no set hours who can go 'it's raining, time to taxi some people who don't want to walk or cycle today' synergises well with active transport and transit.
