From our Swindon correspondent:
But I suspect this can be dismissed by something we all know very well: the roads are generally busier on Mondays. That uptick is from Sunday to Monday. If you look closely, it’s roughly where Thursday and Friday the previous week were. This is normal. This is why the congestion charge doesn’t apply on weekends: London’s congestion problem is mostly Monday to Friday.
Now, OK, this hasn’t been seen for a few weeks, but I suspect this effect has been masked by more and more people switching to working from home, but at a certain point, you’re going to hit a base level which includes only the necessary workers, and for a lot of them, they still skew towards Monday to Friday. Your bins are collected on a weekday, farmers markets take place on weekdays, you won’t get a PC repaired on a weekend and so forth.
