you haven't lived until you've had an 18 wheeler pushing you down the road at 75 mph 6 feet off your rear bumper in heavy trafficgod forsaken southern city (bc of their drivers) ... tailgating mercilessly
its especially thrilling if you are piloting a toyota yaris or similarly unsubstantial tin can type thing
i've never had it happen anywhere except the mid south and i've had it happen many times there
