I think motorcyclists should pay more for health insurance insurance considering they will use it way more often no matter how well a driver they are, the risks are simply always present.
I don't see why not. Maybe no need to ban altogether, but a heavy tax on both might be useful. For motorbikes maybe just exclude accidents from coverage.
There's a long list of topics where this particular reasoning could draw a line somewhere. It is unfeasible and pointless to cover them all unless they are all banned or all allowed (this essentially is the current state +- AFAIK).
I'd say it is worth looking at redrawing that based on the maximum effect achieved. Drugs would be at the top of this list, followed by motor vehicle use and unhealthy foods. There is probably not enough justification to go beyond the 3.
I’m not clear on what the effect actually is. If it is cost reduction, not sure where motorcycles should be on the list (they are probably more costly for life insurance agencies than for health insurance ones…).
I guess I’ve been beating around the bush, but my point is that targeting drugs specifically for this sort of thing would seem kind of, I dunno, puritanical to me (as someone who doesn’t partake). I’d rather just insure everybody and hope they don’t hurt themselves, just out of their own self interest.
