If the green is a bike lane or path that intersection design is
completely screwed up. I would never advise anyone to stay next to a
truck there. With my comment I meant cycling facilities designed by
competent traffic engineers, not by incompetent ones.

So did anyone report in _detail_ _how_ these accidents started? What
precipitated them? Did the cyclists blindly trust their rights? Usually
there are tire marks and such when a cyclist hits the brakes hard. Were
there? How long? Speed? Et cetera, et cetera.
Sure, the motorist is nearly always at fault in such situations.
However, I have, especially in Germany, seen cyclists blow through
intersections at high speed without as much as even a slight head turn
to the left. One guy proudly posted a video in the German NG where
someone (might have been he himself) blew through a city at full speed.
Just watching it made me cringe.

1. Go and measure the remaining width of the straight-ahead and
left-turn lane. Sans bike lane. Then you will realize that even a little
Isetta would have trouble getting through there without violating the
required space to cyclists. Now imagine a big van or truck with the
driver being in a hurry (like you were on the bike) barreling through there.
2. The left turn "bike lane" also reduce the left turn lane to way below
regulation width.
3. The left turn "bike lane" is way too short. Maybe they only have one
bicyclist in that town and figured it suffice for him or her.
4. They didn't even bother to write bike lane or a symbol on either bike
lane in the area leading up to this intersection. Has paint become so
expensive in Germany that it would have bankrupted the village?
5. If people come around that corner too fast there is a simple
solution: 40km/h speed limit or less. Or do you think it's ok if they
run over a kid that happens to be in the road? Or crash into the back
end of a traffic jam?
This is almost the classic case of gross incompetence on the part of
whoever designed this "solution" and those who signed off on it. If
people are too incompetent to get it done right or if it can't be done
correctly because of existing buildings then don't build a bicycle
facility at all.

You've got such lowlifes everywhere. Unfortunately they keep their
driver license until something terrible happens. And even then they
sometimes keep it. Most people don't report such incidents and that
fuels their "success".

Sure you do.

The amount of road rage I have seen on German autobahns is beyond

They don't. If a guy with road rage shows up nothing will stop him,
signs don't matter.

Now that was a serious mistake. If you had a witness and the license
plate info then that meeting cannot possibly have been as important as
getting such a knucklehead off the road. Why did you not at least
exchange names and phone numbers with this witness and got in contact
later that day? That takes less than 15 seconds.

Exactly, and the lanes on the road in the intersection area are way to
small. An accident waiting to happen. Now look at my link again and you
will see that they did not make the mistakes I listed farther above.
It's not that American bike facility planners never mess up but after
having lived long enough in Germany, the Netherland and the US I can
rightfully say that the German bike facility planners are the worst of
the three groups. By far.

Sorry to say but that being a model project confirms my belief that bike
infrastructure planners and "infrastructure scientists" in Germany are
largely incompetent.
