Road *speed* signs certainly, but what is the possible safety impact
of having intercity *distance* signs in either or both units ?
I suppose I could go with both being available - it makes no sense with our
(milometers) odometers but visiting (driving) tourists may find them handy.
It seems you are only in favor of coexistence where imperial doesn't
already have a monopoly.
Sorry if it seems that way - as I don't believe that way.
