I have a family letter sent from the US to here, the UK, in 1960 which mentions keys on the rear of cars - 'useful as a bumper when cars pile up on the freeway'. Please can anyone explain what these were? And what they looked like? Apologies if this is a really stupid question but I haven't had any luck searching the web.

I have absolutely no idea what they're talking about...
