I never got why people even had the idea for solar bike paths etc. We have literally millions of roofs that are still empty, where noone tramples on, that are angled so any snow and water will slide of easily…

Lets fill out those first and if will still have demand for more surfaces to install solar panels on, then we can think about putting them on the road… (it would still be stupid)

The best try I’ve seen was a bike path and iirc even that was a miserable failure. Making roads out of glass is stupid and doesn’t work, who woulda thunk.
