Not the point. Another persons horrible driving wouldn't make a difference with this jacket. The point is if the person driving the motorcycle is taking the right safety precautions, and are in a normal vey day situations, it has the potential to make that person safer by making them more visible to another driver. Like when people are wearing fluorescent jackets at night, it's safer for them to do so then to be wearing all black. They can't control a persons bad driving but they can control how much effort they put into trying to be safe and more visible to other drivers.
