As opposed to being able to just freely walk around as you please? You could say that, why not. And if one insists on moving a 2 ton metal cage through a city going 30 mph or more, I think having to wait now and then is a reasonable trade-off. The natural habitat of the car is the highway and that's where it should stay.
