Restrooms, drinking fountains, sinks, doorknobs, street crossing buttons (etc.) in the time of pandemic

(Although this is like initiatives from Portland City Repair and the UK Road Witch project, the first Parking Day in San Francisco, which I been writing about for 10+ years.)

One of the responses to stay at home orders and the pandemic has been shifting road right of way use away from cars towards pedestrians and cyclists, both formally through actions by local governments and informally by activists ("https://wtop.com/dc/2020/05/activists-block-off-dc-streets-to-create-socially-distant-outdoor-space/," WTOP radio; "

The Washington Post ran an article, "Coronavirus may never go away, even with a vaccine," making the point that covid19 will be with us "for a long time" even forever and whether or not there is a vaccine or herd immunity, elements of public space will have to change. From the article:

Eventually, many experts believe this coronavirus could become relatively benign, causing milder infections as our immune systems develop a memory of responses to it through previous infection or vaccination. But that process could take years, said Andrew Noymer, a University of California at Irvine epidemiologist.

Doorknobs and pedestrian crosswalks. From the article:

Communities should be thinking about installing doors that don’t require grasping a handle, and re-engineering traffic signals so pedestrians don’t have to push crosswalk buttons, said Eleanor J. Murray, an epidemiologist at Boston University.

More elements will require redesign.  Like putting flags at crosswalks that people can wave when they cross the street.  Maybe people will have to own and bring their own flags.  Although the flag intervention is too accommodating of car-centricity.

Restrooms and sinks. We will need to wash our hands a lot more frequently, throughout the day, regardless of where we are. Do we create a "network" of sinks in public spaces? How do we keep them clean? Can they be activated by proximity sensors so you don't have to turn the faucets on and off?

Many communities don't have "public restrooms" ("Restrooms as an element of the public realm," 2018). If that changes, how do we keep them clean?  Do laws and incentives change so that privately provided restrooms such as at restaurants and hotels have to be open to non-customers?

Drinking fountains. I've argued for an expanded network of public fountains ("Why not get office buildings to install water fountains in facades as a community amenity?," 2019).  London's been doing this.  Some supermarkets even have outdoor drinking fountains for dogs.

That doesn't seem practical now. And for all the about how bottled water misuses water and creates plastic waste, especially when local water sources are often superior to bottled water, we'll need to bring our own water.

But instead of buying it, people should be encouraged to have their own containers.  Many cities, including DC and Metropolitan Washington with the "Tap It" program, have created a network of businesses that have agreed to fill up people's water bottles.

What else?  What other urban elements will require redesign?  Obviously, transit is one.  What else?
