I'm from Germany. Our truck drivers aren't even considered particularly insane in global comparison, I suppose. Yet you often see them tailgating, minute-long overtaking because the difference in velocity is just so small, going leftmost lane, and so on. Basically the only thing a truck can
Perhaps the speed limiters have something to do with this?
While I have seen truck drivers do some questionable things on occasion, most wrecks I've seen involved some idiotic driver in a car.
That's most likely because cars outnumber trucks by far
Sorry, I should have been more specific. When I see an accident involving a truck it was usually the driver of the car that was the cause. Not that I'm saying this is always the case. I have a friend who was almost killed by a truck driver who ran a red light. There are also many roads in the US where the truck traffic is equal to, or even more than the car traffic.
Well your place might differ (though unlikely) but over here every other track is tailgating either a slow car or another truck.
I don't see trucks tailgating cars very often. But I see them tailgating each other on occasion.
