Drivers can reform their gas-guzzling ways.
But they don't. Henning works in a studio near Corinth Square Shopping Center in Prairie Village, where he has watched folks drive from the Hen House at one end to the dry cleaners at the other - a short walk away. His biggest peeve, though, is drivers who sit in line at McDonald's, windows rolled up, air-conditioning blasting, engines idling for minutes on end. Thanks to his gas-saving system, Henning needs to fill up his '97 Jeep Wrangler only every other week. Henning thinks fellow motorists would rather gripe than change their ways.
