In the same universe, how logically and justly do you both fine car drivers who don't wear seat belts and permit motorcyclists (who can't wear them) on the same roads with them? If you're fining car drivers for not being safe, how much less safe are motorcyclists? That amounts to fines for being a little unsafe, and no fines for being a lot unsafe.

Clearly, then, it's not about safety. It's about revenue generation.
