But this still doesn't address the problem of the defaults, which *do*
vary by region to region (such as only one other state allowing left
turn on red from a two way street, contra to the national default).  If
you have suggestions, please pitch in; since this also solves the
existing problem of all intersections with a stop sign or traffic signal
being restriction=no_u_turn by default.
