Just an observation. About a quarter of a mile from my house a footpath goes over the M4. During the first lockdown, in the time it took me to cross the bridge I might have seen 2 or 3 vehicles pass. This afternoon when I crossed, although the volume of traffic was considerably lower that it would normally be, there was still a steady stream of cars, vans and lorries travelling in both directions - significantly more vehicles than in April. Perhaps this will reduce in the coming days, but if I worked in a hospital I wouldn't be planning for any lazy weekends in front of the TV any time soon.
