It always struck me when I first used GPS driving around Cornwall, that
the next logical step is a short range vehicle position transmitter so
that the GPS system knows where the other cars are and tells one of you
to stop at a passing point when the next stretch is blocked :) Of cause
you still have the problem of who moves first but most of the time you
will not be stuck having to back up all the time.
