I have now decided that pointing over the roof to point by on the right is not a good idea. In this election year, I am not flip flopping. I am "clarifying" my previous position.
At Thunderhill, I tried pointing to the right inside the car, and it was both easier and felt safer, what with all the lunatics around me. Oops, I mean calm and considered fellow drivers. Also, if my point bys looked like I was waving away something annoying, that's pretty much what I intended. (OK, you're faster than me, now stop bugging me.)
