One risk factor that the two-dimensional geometry of OSM won't show is how a curve is banked. Unbanked curves are common, and I have encountered some curves that are banked with the low side of the curve towards the outside, very risky under wet conditions.

Zoom in!
  If there are enough nodes you should be able to see how sharp the
corner is ..
I use this is fog! You are travelling very slow and cannot see too far
.. the GPS map gives you more than you can see.

-------------------------
There are speed warnings - usually for fixed speed cameras. And some use
this for land mine warnings. No reason why the same method could not be
used for corner speeds ... but this is not part of the map but separate
POI.
