I don't understand that comment... I am not declaring anything - at worst I am making an incorrect assumption to catalyse a bit of a debate (which seems to be working)...
How do we show the difference between legal and physical restrictions? Looking at the wiki page for the access tag, its opening sentence is: "ACCESS VALUES are used to describe the LEGAL access for highway [1]=*s and other facilities..." Further down on the same page, the physical restrictions are discussed, where you can find this sentence: "A number of statutary restrictions based on height, width, weight etc can also be defined." Both of these address what is "allowed" and not what is physically possible. Hence you are right - access applies to both obstructed and unobstructed routes, and the characteristics of the obstruction itself are a different subject. For a bridge with maxweight=2, we have no way of telling (from current tagging) whether a 10-ton fire truck will cause the bridge to collapse, or if the restriction is there for political reasons to keep heavy trucks out of residential areas or country lanes.
