I saw the Knutschen ad when I was in Germany this summer. Cute! The speed bump ad dialogue has been accurately translated here, nice job.

Strangely enough, I didn't notice speed humps in Germany, although I rode my bicycle a fair bit. Lots of little traffic islands, though. Something I liked was a lack of stop signs--they use yield signs as a rule, a real boon for everyone, especially cyclists. In North America, people freak out if a cyclist doesn't put a foot down at a stop sign!

Greetings from Victoria, British Columbia

I'm really sorry to hear about the child that died on your street. I have a suggestion by way of a story that I heard some time ago. There were some folks in a neighborhood like yours (a child had died and a speed bump had been requested). They got tired of waiting, and waiting, and waiting, and being put off, and dealing with endless red tape for years, so they finally took matters into their own hands. One night they went out and dug a speed ditch. Oddly, the city showed up the very next day to fill it in, and the crew added a little extra on top to form the perfect speed bump they all been wanting!

Child is killed on 17th street. (Kumo)

All elected including the city Council Speaker and CB4 write to ask for one (1) speed bump

DOT is reluctant to study because rule book says there should be two (2) speed bumps on long blocks and there is construction on the same block (800 feet away from the accident)

The elected still obtain an inspection
Six elected and community repreesentative convince the planners to proceed with inspection . They agree

Now the engineers refuse to proceed because Con Edison has opened the street 500 Feet away from the orginal request for one week (It is already closed) and this interferes with the second speedbumps we never needed in the first place.

So let me recap
we ask for one speed bump.
We cannot get less than 2
Since the second one ( the one we do not need) has a temporary obstruction ( one Week) we cannot get the first one for another year
Meanwhile children are dying

I've never heard of Toom Baumarkt before, but from its website, I would get that it's a German version of Home Depot or Lowe's. They sell lumber, plumbing supplies, garden stuff, etc.

They probably don't sell ready-made speed bump catapults, but perhaps you can build one with materials from the store.
