Agreed...there is NO reason to tailgate someone in the middle lane, ESPECIALLY if the left lane is open. If someone did THAT to me..well, last time I jammed on my brakes for about a tenth of a second, just enough to get a little chirp from the tires....and the guy backed WAY off.....that was about 25 years ago, and I am pretty sure that he never got that stain out of the seat..
