Only by getting to within about 3 feet could I determine that this was an advertisement for seat-belt usage. My other guess was going to be one about vehicle safety: like, when you come home, late at night, and get off the train … check the back seat?
The irony of taking this shot: there was a guy putting on a neon-bright jumpsuit, 2 cars down from this ad, apparently to go to work on the local roadway. Dunno. Suppose he’s worried about being run over? But, wait: he’s not going to be in your back seat unless you’re moving pretty fast … in reverse. Hmm.
Oooooohhhhh. I was imagining it was some kind of public service announcement against excessive backseat driving…
