I had one go at the touch screen and decided that mucking about
with that crazy contraption would probably result in destruction of
the car, so I left the settings as they were. Besides, it was my
boss' car and all the speed limits were in MPH anyway, so it was
best to leave it alone.
In a FWD car, understeer's pretty easily controllable with the
throttle.
And I still hate the Prius!
