Don't try to get philosophical....A man that doesn't like car movies isn't a man that I'd associate with anyway.
I've watched car related movies with Fords or Chevys as the main car. Mad Max. White Lightning. Two Lane Blacktop. American Graffiti.
The movies that you mentioned had plots. Just because YOU didn't like them, that isn't sufficient grounds to say that they were pointless.
There are lots of movies that I don't like.
Most of the Fast and Furious movies have plots but I think that they are outlandish and stupid, in my opinion.
