NASCAR (and other....?) racers aim for the scene of the crash if they come around a turn onto an accident in a race. The logic is the other car will have moved by the time they get there.
I find myself working really hard to avoid ped.s on the Brooklyn Bridge. The giant yellow line painted downt he middle of the path and the drawing of walkers on one side and bikers on the other side seems too cryptic for many of the visitors to my fair city.
If I have time I point at them and then point to where they should be. (I'm not great at hills and the bridge gives me ample time to do this. Well, half the trip on the bridge!) Oh and I yell a lot. Really loud.
