I remember watching a series in the 80s about a car. It wasn't Knight Rider and I don't think it was Automan. It was a cop or detective-type guy who had a car which, when it went round corners, did so at right angles.
He always dreaded getting in the car, and when the car went round the corner he was thrown up against the window inside. My brother and I always watched it but it wasn't on for long... and everyone I ask thinks I'm nuts!
