I will look into the above stuff and will ask more questions if needed.

there is

However if oyu are looking for unexpected sharp corners you need to look
at hazzards.

[Simon Poole]

Potentially an argument could be made for
http://wiki.openstreetmap.org/wiki/Key:turning_radius

While it is true that in principle this could be derived from the way
geometry, in reality for the use case for which the tag was designed,
the geometry is typically not available in enough detail (in the case of
logging vehicles there are further considerations too).

Simon

PS: while OT, I would suggest not relying on a navigation device to
determine how fast you should drive/ride on an unknown stretch of road
-particularly- on a motorcycle.

[John Eldredge]

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.

Geometry of road is already providing this information, there is
probably no need to duplicate this in tags.
