“on a personal level I’d feel (and know many others who’d feel) extremely uncomfortable or foolish fressing on a sidewalk in the street.”
so I spent All Shabbos looking for a solution for you. I think I found one that just might work. You need to halt kup a bit as it is veyr complicated but probably worth the effort as it will entirely solve your conundrum .
Ok here goes now, bear with me, if you feel uncomfortable or foolish ferssing in the street, then, and I know this is crazy but just hear me out, don’t free in the street .
This step should entirely solve your problem.
LEt me know if it gets confusing
