Obeying traffic laws is the right way to do it. The screaming at him, yes and no. Cagers tend to take one of two approaches. One, the man has a conscious and will feel bad about almost causing you harm, and will be careful in the future. Two, thems fightin' words, boy, and will get a kick out of harassing hippies all day. I still yell at those who are asleep at the wheel, and cuss at those who are blatantly dangerous, it's human nature to do so, but I've made a concerted effort to temper it down. A "You about damned killed me, be careful" or just a "watch it" tends to show more shame in the drivers' eyes and less flames of hatred.
