My Thai neighbors were riding a motorcycle with a sidecar late one evening a few months back. They were hit by a drunk driver and both hit the tarmac quite hard (both without helmets). The wife spent a couple of days in the hospital whilst her husband were in a coma for 3 weeks. After almost a month at home without being able to work, he is now back at work and on his motorcycle without a helmet. I offered him a helmet, but he said helmets are so heavy, so he stick to his baseball cap.
