What's so wrong with helmets?
And nothing is wrong with the idea of safer flights by banning weapons.
The implementation is crap and (mostly) useless though, in both cases.
If bikes _need_ to wear helmets, that's just taping about other problems. If bikers cause problems on their own (crossing red lights, driving insane and ignoring the law) I'd suggest that they wear helmets or stop using that bike.. If bikers are regularly hit by idiot car drivers and 'wearing a helmet' seems to help, soemtimes, somewhat, maybe, then the problem is elsewhere and should result in
- harsher penalties for the car drivers (20 times the mass, 80+ times the horsepower). Let them bleed in court, if the bikers bleed literally
- better infrastructure (note that this is point 2 for me. There's no excuse for being an ass even if there's no dedicated bike lane)
So .. the question you totally ignored is 'Why helmets in general and why do people force them on others in the first place'. Why?
