As for the rules of the road, agree that all vehicles should follow the rules of the road, and it would be helpful if the drivers of cars could set a good example for the rest of us. Maybe they could start a) obeying speed limits, b) stopping completely at stop signs, c) signalling when turning, and c) refraining from driving while intoxicated.

If you strike the right humourous tone maybe you could accomplish your mission of countering his drivel while being upbeat. Good luck and I hope this helps.
