As per the title really... Is there a road or route that you have used previously, but have now given up on as a lost cause?
Considering doing just this, for my own nemesis, the A70 through Currie (also, unfortunately, the stretch of road outside my house.)
In 3 years of almost-daily commuting, I can't remember when I have travelled on it without receiving a close pass of some description.
It's mainly the domain of single-occupancy vehicles. Add in the unassailable entitlement to use it as such (as evidenced in the debates of the West of Edinburgh school mergers).
So is such a realisation/conviction a step down the slippery road of giving up on biking in urban Edinburgh? Or are there others that have deleted certain routes from the route map with no long-term effects?
