I think the video game folks will be coming out with a "Turnpike Shooter" game one of these days, if they haven't already.
"How many unsuspecting tourists, vacationers, and just plain folks can you kill before the police gun you down? Pick you choice of weapon, your favorite highway, and let the fun begin! Play 'Turnpike Shooter' today! Available at all stores!"
