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
