I'm in the EU. This road does look a little bit hazardous to me; like it was designed 60 years ago and never updated.
- The area one is not supposed to drive in doesn't appear to be marked. Where I live, it would be painted with yellow diagonal stripes.
- On a high-speed road, there would be grooves on the road to generate noise if you are driving too close to the edge of the lane.
- Paint on the road is rarely the only signal to the driver (because of snow or other conditions that may obscure road markings). There would be ample overhead signs.
- Unusual obstacles would always be clearly visible: painted with reflective paint or using actual warning lights.
- We rarely use concrete lane dividers here. Usually these areas consist of open space and a shallow ditch, so you don't necessarily crash hard if you end up driving in there. There's usually grass, bushes, etc. There are occasional lane dividers, of course, when there's no space to put in an open area. However, the dividers are made of metal and they are not hard obstacles and fold or turn your vehicle away if you hit them (and people rarely do because of the above).
I'm sure there are some dangerous roads here, too, but a fatal concrete obstacle like this, with highway speeds, with almost no warning signs whatsoever, is almost unheard of.
