Hi redstu,
This the one you mean
Vanishing Point (1971)
Kowalski, the hero of the story, works for a car delivery service. He takes delivery of a supercharged 1970 Dodge Challenger to take from Colorado to Frisco, California. Shortly after pickup, he takes a bet to get the car there in less than 15 hours. After a few run-ins with motorcycle cops and highway patrol they start a chase to bring him into custody. Along the way, Kowalski is guided by Supersoul - a blind DJ with a police radio scanner. Throw in lots of chase scenes, gay hitchhikers, a naked woman riding a motorbike, lots of Mopar and you've got a great cult hit from the early 70's.
I think there is a more recent version but doubt it is as good. Keep a sharp eye for the naked chicks on motorcycles
Yes a bit dated and a lame story but some good scenes as i recall. Enjoy.
