I read the fundraiser link posted on The Thaiger. It says that he had valid travel insurance. However, it seems that his partner was wearing a helmet, and walked away unscathed, and seems to indicate that this guy was NOT wearing a helmet. The fundraiser states that the insurance is not paying. I would guess that it won't pay because either he didn't have a legal driving license, OR the fact that he wasn't wearing a helmet.
So many people think they're covered no matter what. They should read the fine print.
This is really sad.
