look at slide one on transport use. No real drop off until after lockdown and the first to taper off was the tube.
It doesn't tell the whole story of course, but schools only started closing W/C 16th March. My wife works in a factory of 250 and when she finished for holiday on 20th March the only provision was hand sanitiser stations around the shopfloor. All was as normal in the place.
