Its really just human nature that folks learn from their mistakes rather than have an understanding or some foresight of the consequences of their actions. It all really just boils down to a lack of experience. Take for example driving in the snow and controlling a vehicle for slippery conditions. In countries such a Finland, driving in snow conditions is par for the course.

It can also be fun getting that experience for when conditions get really bad.
