Karrie that is something that has bugged the hell out of me for years. If you want to build a car to sell to the general public: It has to have steel beams in the doors to guard against side-impact, At least two air bags in case you hit something, Roof roll-over protection in case you roll the damn thing, crush zones front and back to lessen the impact.
What does a motor cyclist need? A crash helmet?????? G.F. Strong Hospital in Vancouver is full to the brim with paraplegic and quadroplegic Goddamn bikers that out medical system is paying for. While we are abolishing cigarettes, why don't we abolish motor bikes as well.
I'd just as soon speed limit them and toughen up traffic laws. In this day and age, abolishing small engines isn't going to help the environment much. The day we start trying to eliminate all risk and danger entirely is the day we become a pretty crappy place to live IMO.
