If legislative or market forces don't curb the size of personal vehicles lumbering down the road, drivers who choose small cars will remain at serious risk. If our lawmakers are unwilling to address the various negative consequences of rampant SUV use, they can at least promote the beloved Second Amendment by arming small vehicles with sufficient firepower to be able to blast their way out of an impending collision. On-board automated weaponry would be restricted to vehicles below a certain gross weight to assure that owners of mammoth vehicles didn't pile on more advantages.
You guys work out the details. I'm just the visionary.
