But it's really not much like an authentic town center in the types of amenities it has and, while you can walk to a number of restaurants, I expect you'd still have to end up driving for most things. The area as a whole is not very walkable and there are limited transit options.
If anything it's how they're used and how the automobile infrastructure (roads/highways/etc.) is constructed.
In reality there are more purposes to cars. We shouldn't therefore apply some aspects of cars to the broad meaning of car culture.
No, I believe that they're talking about the ubiquitous need of a car for any given task. It would be nice if areas were designed such that a vehicle wasn't required to do more or less anything, be it restaurants, entertainment, general shopping, etc.
I'm not really sure what you mean by "We shouldn't therefore apply some aspects of cars to the broad meaning of car culture." It sounds like simply semantics at this point, that is, you infer a different meaning of "car culture" than the OP presents, but I don't feel that detracts from the point about the constructed necessity of cars.
