I can’t say that’s “unbelievable,” but it is stupid.
As a rider myself I support helmet laws. Here’s the way I see it; if riders can show that they have enough insurance to pay for their care for the rest of their lives in a vegetative state, then fine. Go without. As long as you don’t become a responsibility of society. OR...if you can guarantee that you will die after such a wreck, then that’s OK too.
That’s why I always wear mine.
I have become quite fond of ALL my Brain cells, and don’t want to lose any of them.
