Why? I'd think folks would appreciate the warning that the "compact" labeled parking spaces are too small to safely park a larger car or truck.
Now ... the "fuel efficient" parking spaces are just feel-good silliness.
HA...YOU don’t live in Oregon, do you? Compact is another euphemism for “green” or fuel efficient, and many parking lots have almost all spaces as “compact”...and, I DO NOT NEED a warning on where to park my Ford 150 pick up...
