It was repealed on the basis that it was not up to the government to prevent people splitting their heads. The insurance companies pissed and moaned and some quack from the Cleveland Clinic wrote numerous screeds to the paper that it was so heartbreaking fixing the people who were splattered without helmets. I wrote, in response, that he probably picked the wrong profession and he should bitch about his guidance councilor instead. The paper declined to publish it...
I am the first to admit that Ohio is an incredibly stupid state, but the helmet laws have nothing to do with it.
