I was reminded of this situation in the thread about a cyclist getting sued by a motorist whose car was damaged in a collision. This situation happened to me, with me as the motorist, and I nearly hit the guy who tried to cross in front of me as I turned left. Motorists are NOT expected to look behind them for traffic coming up the street the wrong direction when making a left turn. If you come up behind someone like this, it'd be real easy to get run over.
