Sorta puzzled at the folks that evidently think the O.P. is concerned here about something that's "none of his business"-? I frankly think a call to the Highway Patrol was in order since the idea of sharing the road with a massive, grotesquely speeding "guided missile" is unappealing to me.
But maybe that's due to my Mother's having been passed by a speeding vehicle one fine morning, and in the next moment she saw the within-the-speed-limit pickup he next slammed into from behind (at "only" 80mph or so) go sailing straight across the freeway right in front of her. It tumbled fifty feet down a bank to land upside down on some railroad tracks. The driver of the struck vehicle and her 12 year old son were killed.
So, yeah- it IS our business!
