Road hazards

It always creeps me out when I see something like this, we were slowed down because of a rear end collision

Why does that freak you out?

It was on a 65 mph highway and it would probably take a 20 mph impact to push it through a windshield and into someones face.
I think it should have had a chase car following it.

It all depends on what a specific state requires on oversize load vehicles. While not needing an escort vehicle this operator should have enough common sense to hang a couple of yellow flashing lights on the furthest most rearward portion of his load. Flags don't always cut the mustard especially in dim or no light conditions.

Not sure which one I would rather rear end...

Must be going on a long trip where there aren't many gas stations.
