Yesterday I was about to paralell park on Wells street just south of North Ave(for any Chicagoans) it has a marked bike lane. I find an empty spot, so I pull to the right, check my mirrors, start to reverse it in the spot and during this manuever a cyclist in the bike lane rode by and SLAMMED his palm/fist on my car. At first it scared the sh** out of me. My first impression was to chase down and educate but I went into Zen, finished parking, fed my meter and continued my errands. Instead of that SLAM BAM on my car the cyclist could and should of rode to the left...what do you think... When I checked my mirrors I did not see him (no light and it was dark). I feel he saw the 3500 pound Crown Victoria with reverse lights on????
