In general I don't find Colorado drivers to be courteous. I see people drive aggressively everyday including well over the speed limit, tailgating, cutting people off and never yielding to someone even when traffic is near stopped and doing so wouldn't cause someone to be delayed. And don't get me started on the plethora of cars with severe damage, bald tires, no windows, inoperative lights, etc. And a cop pull someone over for speeding or defective vehicle? Heck no, I drive 50 miles each way to work and never see that.
