Obviously there's a limit to how reasonable multimodal transportation is. Nobody's expecting decent transit among rural farmland. But we could do better than we're doing now -- MUCH better.

The biggest problem with this is that in the US you usually have to choose between one of two extremes which dovetail with your examples. You're either in a big ugly apartment block downtown (or in a downtown-ish area) or you're in a super low density suburb where Cars Are Law.

Plenty of countries manage to have more of a gradient, where you can have, say, suburbs of middling density, where driving is easy, but so is walking, biking, and taking the train to the city. I live in Munich at the moment and the suburbs nearby fit this mold perfectly, but in the US such towns are extremely rare.

There are still plenty of cars in Munich proper, for that matter. There are just lots of other options too.

* Also in most American cities even the downtown still isn't very walkable, definitely isn't bikable, and has crappy transit. There really are only a handful of cities in the US where these things all work reasonably well.
