Agreed, a few more of the bad guys being cars would have been nicer, but they showed a cyclist without a helmet so there's a plus. The guy standing in the road at the end needed to be run over by a taxi as the credits rolled (or at least have one stop tight to his legs and abuse the fark out of him) if they wanted realism. I wonder if going cycles and motorbikes was the thematic decision that's being presumed here, or a directorial decision because you get obvious human beings a lot quicker that way, equally the cars being top down convertibles.
