Super Speeder law is win. Most cops are greedy and won't pull you over unless you're "super speeding" So you can get away with doing 75-80 with little fear of being pulled over. That being said, If you're speeding at all be prepared for the consequences and don't complain. You knew the rules.
Nerve of those Police.. giving speeding tickets for 20 mph over..
After I purchased a GPS I stopped speeding. After seeing I decrease my 45min drive down to 41min by going way over the speed limit, I realized it really wasn't worth it in the end. I can understand that on a long drive speeding cuts a significant amount of time off in the end if you're consistent, but 10 over is good enough and usually keeps you free from trouble if you're really in a hurry.
