We have all had this scenario run through our heads at one time or another. It's so common there have been commercial parodies surrounding it. Guy sees pretty girl while driving car and crashes car. We are human and sadly many of us cannot control our base level instincts.
Thankfully, most of us we snap back to reality and continue driving on when we are faced with this scenario.
Unfortunately this young buck on a scooter in China was so enamored with a woman walking down the side of the road he veered into a truck and caused another motorcyclist to run into him, creating a mini pile up.
Moral of the story? Keep your eyes on the road and pull over to ask the girl for her number. Maybe joke that you did so because you didn't want to get into an accident like this guy.
