I often let right turning cars go to my right and also sometimes get appreciative waves.

In a unrelated situation, yesterday morning I was in the middle of the go straight lane and first in line and a car pulled up to the right of me in the right turn lane. I did think it was odd they were not turning right as there were no cars coming on the x-street. Oh well I thought, an extra cautious driver. But then on green I proceeded and found my self being squeezed to the left by this same car going straight from the right turn lane, we were head to head and I 'signaled' at them and they kept moving leftward into the middle of the intersection, so I had no choice but to brake and pull in behind them. I was not a pleasant experience.
