Did you try taking public transit at 2AM? In many cities, the public transit shuts down at some time in the evening, forcing people to use cabs (or Uber). It's great if a city has decent public transit, but there's a reason why other services have a role: some people are in a big hurry, others are caught out at a time when there's no public transit available. There's also plenty of cases where the public transit option just isn't very good for a particular route (such as, in the NYC area, try going from Jersey City to Staten Island on public transit).
