You are watching the trailer of little known movie vanishing point.

I watched this movie at my nextdoor neighbours house being babysat.(I was about 10 years old)
I had chinese takeaout for the first time. It must have been in the mid 70’s (no not the temperature, the year!) 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.
