Per "Tom $herman (-_-)"
":
Here in the US, some of the worst aggressive tailgaters are company
vans. Although why people getting paid by the hour are in such a
seeming hurry is a mystery.

I think it's something to do with the driver's position and the
lack of a hood. I've noticed at least one co-worker that
tailgates mercilessly driving a full-sized van but drives
normally in an automobile.
