If one guy is tailgating you, he's the problem. But if there are 5 piled up behind you, then
you are the problem!
Like you said, most on the Turnpike around here are doing 90, so stay the hell out of the left lane, if you've got a trailer!
I'm usually the guy blowing past you over 90 mph, but I don't tailgate, as I don't want the stone chips. I'll hang back a respectable 4 - 5 seconds distance and flash you to move over, then blast past you once you do. I hate riding as a passenger with any driver who tailgates, which really describes most IMO, so I nearly always end up the designated driver wherever we go.
Anyone remember learning the "5 second rule" in driver's ed class? Basically, you start counting when the car ahead of you passes a landmark, whether that be a telephone pole or sign post. If you reach that landmark before "five Mississippi", then you're following too close, it's time to back off. I believe this roughly corresponds to the "1 car length per 10 mph" rule, that some others prefer. I adhere to this everywhere except the Shure-Kill Deathway (I-276), where allowing even 1 car length gap in front means being constantly cut off.
