I quite like the 2020’s hobby of cycling every route within the confines of whatever area you are locked down into, then blog posting your map.
It reminds me a little of the Degree Confluence Project - photographs from completely arbitrary places, distributed evenly around the earth: https://www.confluence.org/
I’ll also randomly switch persons to avoid making someone uncomfortable, and I’ll follow from 1-2 blocks away.
