Addressing the 'slower and more courteous' question, I've just been shopping and the traffic in some roads is up to I'd say 90% of pre-covid levels, whereas on side streets and, curiously, the main A38, it's still maybe half of those levels. I'd say it seems less courteous now than when there was very little traffic in the first few weeks of lockdown. Certainly less willing to wait behind a cyclist or let people cross the road other than at an official crossing. Speeds about the same though.
