Instapundit linked to this, but I do work at a couple of mines that use the Cat 797 haul truck – payload capacity: 400 tons.

Note that the center axle height on that haul truck is about equal to the roof of the cab of a pickup truck. If a haul truck runs over a pickup, the haul truck driver might very well not NOTICE.
And the highest point on the remains of the pickup will be about 18″.

That’s a Cat 785. Its payload is less than half that of the 797.
That’s why they make you take a special “In Pit” driving class. Pretty much everything in the pit is bigger than you, and can ruin your whole day.
