"A car club or automotive enthusiast community is a group of people who share a common interest in motor vehicles. Car clubs are typically organized by enthusiasts around the type of vehicle (e.g. Chevrolet Corvette, Ford Mustang), brand (e.g. Jeep), or similar interest (e.g. off-roading). Traditional car clubs were off-line organizations, but automotive on-line communities have flourished on the internet."

That seems to me-if you accept that definition-a car club can take many different forms.

I do share your dislike for street racing that takes over public streets and highways. Not only is it dangerous to the participants but also to bystanders and the general public using the same streets.
