Exclude. 'Steepness' is covered by the incline tag.
There is no mention of width or surface in the smoothness tag.. nor 
should there be. The surface=concrete can be very smooth, rough or 
impassable. Still a concrete surface.

Numbers? Something like?

Very smooth = less than 1 mm bumps (rise/fall) in a  1 square metre area?
Impassable = >0.3 m bumps in a 1 square metre area?

I'm not suggesting measuring it objectively .. but subjectively it gives 
an idea?
