It is somewhat unusual in German as well. You might say something like 'drive carefully' to a friend but it's quite unorthodox for a pub to express something along those lines.
it translates to "save trip home" but is used in a way a New Yorker would say "take care"
a tub tub would not mention driving after drinking
