The true story is ... The movie is from Claude Lelouch.
Its from 1976.
Claude Lelouch filmed and drove the car himself.
Camera was monted on his own Mercedes 450 ( Sound is fake )
He was not drivint that fast ... Wide angle lens always increeses speed perception.
Roads where opened. It was on a sunday morning . Very early in August.
Idea came when he had a full 10 mn 35mm film roll available from a previous movie.
