Both B and I did Transport For London surveys about pre-, current and post-pandemic use of modes of transport yesterday - it was fairly exhaustive in its way, and quite tedious. It took B about 45 minutes because he was at home all day on the sample day. It took me 80 minutes, because it included going step-by-step through Monday when I did two trips on foot and bus in the local area, one out-and-back, the other to Post Office, clinic and shop before returning home, which was actually a very typical weekday for me. They did give vouchers for the time, but I let them give mine to charity.
