How Was Your Commute Today?

[redrhodie]

I need to formulate a simple statement that will convey the idea that "Ignoring traffic conventions endangers us all" but only contains 2 or 3 syllables.

I don't think there's one thing you can say that will work universally, but you can say "use your turn signal" or "pay attention" or "3 ft please".

Not quite as satisfying, perhaps, as calling someone a ^%$#@, but maybe better in the long run.
