If they can't keep up are they really chasing you?
I was stopped by a CHP after I had pulled over to get gas. He said that he had been chasing me for about 5 miles and clocked me at 120 MPH ... he then asked me how long I had been a clamper. We talked for a while and then he left ... NO TICKET !!!
BTW he knew I was a clamper cause of the ECV (E Clampus Vitus) bumper sticker on my rear bumper and my XNGH (X Noble Grand Humbug ... past clamper grand poobah) license plate
Back in the 70s when that 'gas crisis' caused many law enforcement folks to select compacts for their fleet, NBC interviewed a county sheriff from Georgia who was well known for setting speed traps.
About this same time one of the motorcycle imports came out with a lightweight high speeder, I believe called the Bandit.
The reporter asked the Sheriff what he was going to do if one of those Bandits blew through his speed trap when all he had was at best six cylinders in a compact.
The Sheriff deadpanned in the deepest Southern drawl you can imagine, "Well, now, I guess we'll just have to shoot the sumbitch."
