Oh no !!! There are at least 5000 Bollywood films made according to this database:

Has anyone ever watched these kind of films ? Are there any cars ?

I bet there are more dancing and musical scenes than vehicles but maybe some Hindustan here and there and BTW India produces more movies a year than USA..

The only Bollywood film I've seen all the way through was a period movie, so no cars in that. But, yeah, some do have cars.
