This photo was taken in Myrtle Beach, South Carolina. There’s little remarkable about the normative sign, here. Except that a) it is remarkably terse, and b) the driver of the mid-sized SUV parked by it apparently has no idea — or no concern — what it means.
Nor, for that matter, did the drivers of most of the cars parked in that row. All of the spaces in this row were marked “Compact,” and about 3/4 of the vehicles were — this is the USA, after all — decidedly not compact.
