While I do always wear my seatbelt, I do not think compliance should be mandated.
First and foremost the reason why is that we already have more than enough asinine little laws to govern insignificant and mundane elements of daily life. We need to quit having laws made up about everything, cause eventually we wont be able to do anything.
Secondly... If someone doesnt want to wear a belt, So be it, let em go beltless. Fact is its prolly a good thing. Weve got too many people running around as it is, and being at the top of the food chain we have no natural predators, so perhaps we need more things like this to help us thin out the herd. While were at it, can we please remove the warning lables from Windex bottles? Seriously... If your looking under the sink and see a blue bottle and think its raspberry/blueberry koolaid, I say drink up, I doubt were loosing the cure for cancer, and more likely loosing a telemarketer, shoe salesman, or panhandler. You know, Jobs that you can train a blindfolded chimpanzee with full frontal lobotomy to perform.
