Oh no we don't
The question is...why? There is a road and the last I checked we are allowed on those along with other traffic. Just because the inadequate cycle lane is blocked why should be have to get off and walk? Thing is some drivers will now see cyclists going down this road and feel vindicated in blaming all cyclists for all worldy traffic problems. Sigh indeed!
Oh, how much I long to see signs declaring "motorists, get out and push". Ideally on a 'national car route' aka a motorway.
