stick it up your ass. I regularly ride a motorcycle. If its so unsafe to not wear a seatbelt in a truck, then why are motorcycles legal? so you go parrot your stupid seatbelt crusade somewhere else.
Take a chill pill.
You should take a little physics into account with your criticisms. If you dont wear a seatbelt, you have a much better chance of being throw through the front windshield. That happened to 2 friends of mine 30 years ago, one was decapitated, the other cut in half.
Motorcycles are quite deadly as well, and riders are often just as ignoratant of physics, which is wierd, because you use physics a lot when riding.
