The coronavirus crisis and the environment / reduction in transport emissions in particular

I took an evening walk today locally, and even though I've known it for more than a year now, it still feels so strange to me how busy it is around commuting time, but minus most commuting. A few drivers, a few riders, and of course buses, that were clearly on radial trips, but for the most part just people moving about locally, in the parks and streets. It would be perfect, from a sustainable transport perspective, if all local shops, pubs, etc. were open, too, but, of course, the moment they are, much of that local focus will disappear again.
