This thread seems to get fairly sporadic traffic, but maybe it's the best place
to put this ... the button shifter is a pretty stupid design, and like in other
prior-art setups, the Park button should have been placed farther away
from where we can keep hitting it by mistake. I decided to
fix mine.
That page also indexes into a growing set of fixes, hacks, explorations, etc
that I've been doing with the car over the last month or so. Still in process...
but it's like the old "tear your Prius apart" days all over again!
