Two lane road, 60 zone. Im in the left lane, he's in the right lane ahead of me. He's driving an Outlander and going 50. So I go to pass him doing 60. Get about a meter away from him and he starts drifting into my lane. So I slow to 50 and hang back. The car jerks back towards the right lane and then he drives down the road over the lane markers for about 30-40 meters, by which time Ive got annoyed and moved into the right lane to overtake. As I overtake, I give him the ol' two fingers pointing at the eyes gesture which means "look", which he sees. Then at the lights, he starts chewing me out, saying "No need to give me the two fingers, I didnt see you, you were in my blindspot, I waved sorry blah blah blah", him getting angrier. I reply along the lines of "you didnt indicate, you nearly hit me, you didnt even look (I was guessing), dont get angry with me, you were in the wrong not me" etc. At first I was quite nice and polite about it. But it really started to piss me off that he's getting testy with me over HIS mistake, and the fact that his negligence could have killed me, and that he's angry that I tried to get him to aknowledge it. I mean, sorry doesnt help me if Im dead. So this is all pretty standard for most of us. Now, I try to maintain good public relations with the cagers, try to promote a good image for us. So my question is: what is the best thing to say that gets him to go home and think - that guy was right, I *am* a knob, and that *was* dangerous, I have to try better. Instead of: who does he think he is, f*cking biker, f*ck him and the horse he rode in on. Suggestions?
