Below are the results of running over a forklift fork that was left in the middle of the freeway.  The impact happened at 65 mph.  It was at night and the fork was in the middle lane, just after a corner.  I had NO time to react.  I didn't have time to look to either side to change lanes and forget about trying to stop.  All I could do was brace for impact and hope it was a piece of folded sheet metal (I didn't know what it was when I first saw it).

The wheels are ADR M-Classics, size 17x7.5, 45mm offset.  The tires are Summitomo HTRZ-II, size 205/40-17.
