Nice photo! I agree that restrooms are not big spreaders of this virus, IMO and from everything I've read and heard. Of course, the thinking on that and a lot of other things has evolved over the last year.
I took some road trips in 2020 and the only time I felt like there was a hazard was in a shared restroom at a big truck stop, (think airport restrooms), when some guy was coughing or it was just too crowded in the space for comfort. In one-at-a-time restrooms, as long as they have good soap and hot water+paper towels, (so that you don't have to touch door handles), I don't see the problem.
And FWIW, public restrooms that are not kept clean and do not have hot water/GOOD soap/paper towels gave me the creeps before any of this started.
