Yes it is. In fact a pretty thorough study was carried out in Denmark which showed that forcing bicycle helmets has such a big impact on the number of people cycling, that it overall increases the healthcare spending in the country. They did the math, and overall the nation is healthier with lots of people cycling and some getting injured, than forced helmets and no one cycling.

Forced helmets are a great example of lawmaking being driven by ignorance and opinion rather than facts and stats.
