Within 3ft is nearly daily. I'm 6ft so reach from the center of my body is 3ft and plenty of cars come close enough that I could smack their mirrors and understand that close to 2ft because the distance would be from the widest point, my shoulder. I ride in the right tire track well away from the curb and the majority of my riding is on a 4 lane where they could easily change lanes.

Been clipped once on the arm and it busted the mirror and they drove off. Had a Bus just about get me twice. One was a buzz and another the driver passed me and pinched me to the curb at a stop. Looked me in the eye as he passed. It was intentional. Same route likely the same driver. Raised hell with CCT both times nothing came of it.
