Today I would just like to suggest a new rule for London public transport, which I thought of a couple of days ago. If someone is running for the bus just as it’s about to set off, the driver should only reopen the door to let them on if they are wearing a mask. Sat in the wheelchair space, I have lost count of the times I’ve seen people run up to a bus just as it’s about to leave a stop, and practically beg the driver to reopen the door. At least this rule might encourage them to mask up.
