I can't read any of that, but I get that the gist of it is drivers doing stupid things? Texting while driving or the like?
There's a railroad bridge - well, actually a
set of them - going over a street in Cologne that isn't even on the main grid, and for
whatever reason (other than the bridges being a bit lower than usual), non-local truck drivers keep jamming their vehicles under it; over a hundred of them until at least the lowest of the bridges was removed in 2007. The locals call it the "idiots' bridge". At some point, the size and color contrast of the signs warning the truck drivers of the low bridge would've been fit to signal "you're entering the capital now" on a highway,
plus flashing lights.

I still refuse point blank to use a GPS because of the sheer overdependence that they induce. Also have a whole separate rant about how the phone call can wait until you've had a chance to pull over...
The car I'm driving now had GPS when it was handed to me (other than that, I'm pretty much a "map guy" myself). It's handy if you need to drive to a
specific address in a city you've never been in before, much less have maps of, or when you hear of a road block ahead in the radio (assuming that your GPS receives RDS through the radio and thus knows of the upcoming road block, too) and a handy detour through unknown terrain
just happens. (Not that a GPS is outright
infallible, mind.)
