Where do you read that I suggested that tagging completely arbitrarily is an option? There are an infinite number of options for tagging. But there's only one correct one - use objective definitions.

I have no problem with rough observation. What I have a problem with is everyone making up their own definition. Once you've made up the definitions of primary, secondary, and tertiary, I think you'll find that applying those definitions can be easily automated. Sure, there might be some tweaks here and there where we find we need to add exceptions to the original definitions (e.g. a road with speed bumps is never a primary), but at least you'll end up with a consistent system. > Mapping a road "the wrong color" when there aren't any traffic_calming tags >> is another great way to get people adding appropriate tags. >> > > What's so important about traffic_calming tags?
