I don't think I have experienced a day driving in Portland without some idiot riding my bumper within 3-6 ft. Am I missing something? Is tailgating a perectly acceptable driving habit here? I can be going the speed limit or 10 miles over, yet someone will continue to ride my tail even if both lanes are empty on either side. Well no more! Next time i'm tailgated, I will either slow to a near gradual stop, lob full soda cans onto your windshield, or slam on the brakes and collect the insurance. Back off! It's extremely rude, dangerous, and not legal!
