I have ridden in California, Seouth Korea, Italy, England, Germany, Austria, Italy, and Croatia. All require helmets but Korea. They all allow LANE SPLITTING. I just don't understand that you can't lane split but you dont need to wear a helmet. I have been living in Ohio for a 10 days now and my bikes should be here in the next 3-6 weeks. I am not looking forwards to sitting in traffic because lane splitting is illegal. I guess at least I'll look cool sitting there in traffic with a helmet.
