An oncoming Big rig in the center of his lane has the same 2 ft space from the center line.
So when Two rigs meet, at 60 mph they only have a 4 foot space that keeps them from a head on collision @ 120 mph hit.

That's fender to fender. Mirror to mirror is quite a bit less. I've smacked quite a few slower trucks mirrors that drift my way as I pass, and that's going in the same direction.
