I was wearing a fire-engine red jersey on brilliantly-bright autumn day - sun was at the driver's back - but he just focused on making his left turn and "beating" on coming car traffic - I did not register as a "threat".
I sure got him - my hip dented his door and my elbow and shoulder broke out a passenger side window. Of course i did fracture about 20 bones - but it was worth it - I really got him.........
Would a bright flashing white light have changed things? I don't know . Never expect respect from a motorist - it could be fatal........
