Here's a Dystopia fer Ya

Forget global warming-driven famine or a Chomskyan "Hegemony or Survival" future. Consider this bleak scenario that awaits on the nation's sidewalks and in our grocery-store aisles. Squadrons of mobility-challenged Baby Boomers zooming to and fro on their Hoverounds. Oblivious Gen X and Y parents careering around with their supersized SUV strollers. The odd Segway. Ordinary shoe-leather pedestrians in mortal danger.
