It might be an idea to review existing films and decide whether to trim down the amount of 1 star vehicles in them, though I don't think it's right to delete loads of stuff without people's consent. It would certainly free up some space. If a film that doesn't feature that many cars has a few background vehicles (up to about 3 or 4), that's OK but the real problem is the films that have TONS of them, can they all be worth pointing when there's already so many cars in that film?
