Inclines are easy to calculate if elevation data is available. IMHO  
tagging data with incline=* is the wrong solution to an important  
problem, and it signals the beginning of an immense and never-ending  
task of maintaining hard-to-verify data. It would be much better to  
work on a proper solution that involves designing a system for  
registering topographical data within street maps.
