It kinda makes a lot of sense I feel that they'd fit together. You have a form of transportation that is dangerous enough that requiring government licensing is generally agreed to be desirable, meaning that if its the primary option, a government can effectively take away a person's ability to participate in public life or make a living, and easily justify it on safety grounds. Cars are expensive, so a government can both funnel money to its partners in private industry by promoting them, and subsidize them for the populations it considers "desirable" as a means to seem like it has created abundance and luxury (see how how the VW bug came to be for example). And, a society built around cars is one that tends towards physical separation and isolation between people (because of space inefficient infrastructure and relatively quick travel outside of densely built areas), which promotes distrust of others. Thats not to say that cars are inherently fascist or that most people that promote them do so to benefit that sort of ideology, but that if I was some kind of fascist dictator seeking to control a population, Id probably want to push them into buying and relying on cars.

Yeah, thats true.
