You say “knocked off your feet” and “knocked over”. Do you mean the car actually hit you? If you were a victim of a hit and run, I would raise holy hell with the police captain at the local precient because their officers blew you off. Unless you were walking in a local neighborhood, surely some store had camera footage of you being hit.
I agree with the PP about wearing bright colors and working with your ANC rep. Are all of the incidents in the same intersection?
