Cabs are an alternate form of public transit where you pay a lot more per km, especially in cities where the city sets the prices and the number of cabs. There are lots of valid reasons for using cabs over city buses/trains, such as minor medical problems, bad weather, unsafe conditions at night, etc. Of course, once cabs are available, people will use them for convenience rather than the valid reasons. I don't have a solution for this, but I think the valid reasons are strong enough that cabs should be allowed in cities where private cars are banned/strongly discouraged.
