I think that’s limited to the US. In Thailand, kids ride motorcycles from a very young age, and don’t exhibit the crazy driving on that they do here. I think if more families drove motorcycles, it would no longer be considered cool or extreme, and that behavior would disappear. It reminds me of the high drinking age situation in the United States. When people here start drinking, they end up in emergency room, which is not the case in Europe, where they have a much lower drinking age.
The average age of first drink in the us is like 16 years old. The law doesn’t stop anyone from drinking it just serves to ruin peoples lives with a criminal record for behavior a huge percent of people engage with.
