I personally ignore them as others have listed.
I did have a diesel truck pulling a trailer try and smoke me the best he could the other day and then I think it was the same guy moving some things just up the road about 3/4 of a mile parked right by the road in a small yard.
As I went by - I thought "dangit I wish I would have watched him pull in". But after that thought was my next thought - it would have only became worse if I would have known it was him, then this note to self "ignore everything - all the time"!
