The cops won't bother you if you drive 10KM over the speed limit. After that, they might chase you. Then you go 100KM over trying to avoid them before they stop for donuts
I dont cut people off... i'm normally going too fast to cut anyone off. I HATE people who cut me off which is one reason i try to never do it. If i do, i immediately apologize (however i can). I got cut off once and i nearly got out of the car carrying my cars tailpipe that i had just ripped off. I was going to cause him MUCH pain
My area is probably about 50% over 60, so thats why the average person drives 15mph under the speed limit. The main road I drive on to work has a speed limit of 55 mph. You're lucky to get behind somebody going faster than 35.
