Who says Germans don’t possess a sense of humour? ;)
Or let’s call it self-irony at the very least. Due to the arrival of our second child recently our family car park had to be reconsidered, so something with a traditionally large boot entered.
While this resulted in inevitable teasing from some of my colleagues (entering the age, where it’s OK; need to put a hat on the back shelf to blend in with the other owners; did I start a mini-cab firm...), it also came with a surprising discovery. Namely that the very traditional German maker has a sense of humour and offers a ‘wackel-dackel’ as a factory accessory. Which a friend proceeeded to get for me.

I vote for the hat on the back deck (perhaps with feather in the hatband)

Have a hat (sans feather) in the back already. It has a miraculous effect on the following traffic. Since they assume you are an old an erratic driver, they keep more of a distance 
You should post the second pocture to reveal what is underneath - perfect example of taste and practicallity in one piece of handicraft art... [nt]

There is hardly any storage left, with all these accessories! [nt]
I personally like to wear my cap, whilst driving. But the cap is a classic English cap from Harris Tweed with herring bone design. Matches to my left hand car ...
Heh heh ... my wobblin'-head dogs in the boot ....
