now "wider" by the width of the rumble strips. :) I had an aversion to
running over the red and white things, but now, they don't look too much
different from the grass farther in from the edge. I can drive on them
at will now, without flinching. Frame rates up 4 from 32 to 36.
I also tried turning off wall textures, but found I need them to judge
speed. I'll try dispensing with track textures next.
