Element of crime - Kiss & Ridezone

The printer Theo Klahre shows a new designed "road sign" to a young woman at the central station in Halle (Saale). The new sign will be located in front of the central station and shall give travellers who get a ride to it the chance for a short goodbye (with a sense of humor).
After Lüneburg Halle is the second city with a sign of this kind.

Isn't that scandalous? We legitimate kissing in public. That wouldn't have been possible in former more decent times. We would have opened the door for the lady and maybe a kiss on the hand would have been admissible.
But smooching in the face, no!
