Cycling in the time of Corona

Let’s start with unsafe workplaces, and employers who flout the ‘rule’ and force / coerce employees into situations where lives at placed at risk yeah? Then move on from there.
Edit. Sorry, not a dig at you but this stuff boils my piss. Of course, wear a mask but fuck me, having walked (on my daily socially distance exercise) past two building sites today with no distancing or masks in evidence. It’s businesses that are swinging the lead and the government is fixated on blaming everyone except them.

The 15-minute rule for close contact is arbitrary (based on custom and practice rather than empirical evidence). One-metre or two-metre distancing rules (which are derived as much from economic models of lost productivity as from scientific evidence of protection) do not mean that if people keep within these distances, they are safe. The rules mean only that people farther apart are less likely to infect one another.

On this basis, surely everyone must wear masks whenever possible, regardless of the activity they're undertaking?
