On the highway I often put my foot down to get away from these morons. I had an F150 riding me in the center lane on 91 for some unkown reason because the road was damn near empty and the left was clear. So I just put my foot down ran up to about 100 and than slowed back down to 75 when I had some space.
My friend has a very real looking M14 EBR airsoft gun with a laser site. Not that I would because I don't want to get arrested, but I always thought it would be fun to get rid of tailgaters, or those left land bandits.
Open the sunroof and stand up holding the M14 and point the laser site at the offending moron. Watch them move!
So tempting to try, just once...
