Yep. It seems to me that whatever increases the danger and treachery (is that a word?

) of motorcycling will ultimately increase the size of the insurance business as it pertains to motorcycling. That remains true whether the govt requires mandatory minimum coverage, or just that premiums naturally go up as a result of more severe or frequent claims.
Personally, I like when a helmet law is repealed, as it was in Texas. Because when a cop sees you with your helmet on, and you're not required by law to have it, he regards you as a safe rider and is less likely to hassle you over a minor traffic or sticker infraction.
For a short while, the helmet law had been repealed for motorcycles in Texas, but there was still a
bicycling helmet law in Austin. So if you went lidless, your bike had better have a motor on it, or you were in trouble. After a couple of weeks, the city noticed the absurdity of that, and repealed the bicycle helmet law.
