The Metro (trains) stations in my city have foot-operated levers (pedals) to control the elevators/lifts, doors, toilet taps/faucets (though the urinal themselves have sensors to auto-flush), etc.

Although, as a precaution, I carry a hand-sanitizer and fresh mask in my bag whenever I commute on such public transportation.

I guess the pandemic (and the eerie realisation that it can repeat anytime, since it was decidedly an artificial one) has attuned me to be more vigilant on my safety and health, so I try to be cautious and safe in public where crowds can gather.
