My only wish regulation for curbs, is that they be painted or otherwise made to contrast with the roadway. I see too many instances where the sidewalks, curbs, and roadways are of a single material and color and the curb is nearly invisible at times.
For me hitting a normal curb comes with a high likelihood of falling. I've never fallen from hitting a mountable curb (though came close once).
Agree about the color. Most I've seen have been cement or paver while the path itself was bituminous or different colored pavers.
