There were those on my commute for a few weeks. They were resurfacing gogarburn station road, it was closed to motor traffic during the period, but cyclists were allowed through "On the footpath".
Saw plenty of cyclists going through, all of us on the road, none being dicks to the workmen doing the job. This was in the genteel suburbs west of edinburgh: chances of cyclists being dicks are a lot lower here than in crowded city centres
