I think that even with a rudimentary and incomplete knowledge of the road
network one could detect spoofing a car navigation system.   The car would
show up inside buildings and farm fields and lakes.   You'd see this even
on a very poor map.

If the spoofer moved the signal even 200 yards the match to the roads would
be total rubbish and non sense.  It would be detectable even using very old
maps with many segments missing
