Geeze, EOD, you'd have to use I-285 around Atlanta as an example?
What a joke! As far as I know, the speed limit around the whole perimeter is 55 MPH. (There are a couple of sections on the circle I don't get on often....but I think it's all 55.)
'average' speed limit is probably 75-80. It's not unusual to see somebody doing over 100. I've even seen squids on sportbikes with NO HELMETS (Ga has a helmet law) doing high speed wheelies in heavy traffic on 285.
Dammit, EOD, if I were a cop, and somebody came up with the 'everybody' line, I'd be tempted to say "You're right, if you hurry up and take this ticket, I can be on the way to catch the ress of the arseholes!"
