Autocar (what?)

That sounds like the chaotic ownership history of several auto and truck mfrs. I've read about, Jeep, for one. Severe-duty sounds pretty serious,

Very dangerous et threatening too on highways. Once, we got very close to get a piece of this one on highway 90 between Syracuse and Ohio state in 2010. I decided to pass this truck with re-treads and I saw this killer piece flying away right behind it at high speed. We were just behind this truck 10 second before. I never follow trucks too long since then and if I have to, I keep a long distance between them and us most particularly when we are in motorcycle,

Yes, they do have that reputation! If you follow on a motorcycle, that can be fatal. ;-o

Well, you could have knocked me over with a feather, Diane!
I'm astonished! One of the most famous films from Stateside in Britain is Spielberg's first main feature and the one that made his name.
Called 'Duel'.
