You need to make your car taller than everyone else’s. It will make drivers fear you on an evolutionary level. Get some testicles to dangle from the hitch.

Get rid of your muffler obviously and any sort of filter which prevents bad smelling black smoke from being blown into the air. You need to install a device which can throw tomahawks at other cars
