Cyclists expect those who pose the greatest threat to take the greatest care. Invasion of ASLs, blocking exits, double parking in busy streets by motor vehicle drivers can make cycling very unpleasant. The same principle applies to cyclist behaviour towards pedestrians. This is more to do with thoughtful behaviour than legal niceties. Close passes by large vehicles on the road are unwelcome. Close passes by quickly moving cycles in shared or pedestrian space can be just as intimidating, even if they are (rationally speaking) less dangerous.
