We did not feel safe. I did not advise any of these folks that they were breaking the law, or anything like that. But, I'd feel a lot better if there were city employees (police, health care workers, whatever) posting signs, or handing out flyers, or something like that, advising people that there is an ordinance in place requiring face coverings.
In our local neighborhood, Leland Manor, and in Midtown, face coverings and/or people making sure to stay 6 feet apart is much more common, but of course the density of people is lower than on University Avenue. But I did run into a city employee, from city utilities, at a Wells Fargo ATM, with no face covering. I stayed far away until he was done.
Can the city do a better job of reminding everyone to wear face coverings while out in public? The evidence is that face coverings, more than any one other thing, will keep the spread of coronavirus in check.
