Flash your lights twice for radar!
its all about me me me mentality people dont care anymore as long as its not them they dont care but on a side not i ran across 3 elderly folks today who had car trouble to my best guess it was a bad fuel pump i tried to help the best i could and pushed van out of traffic and waited for triple a to get there they were in route from pa to ft lauderdale so i stayed until tow truck arrived and gave them good info for repair shop and hotel it didnt cost me a thing but 2 hours of time no problem there
