BART here in the SF Bay Area still has a mask mandate til Oct. 1. I rode BART yesterday without one and only 10% or so of riders opted to be maskless (including me).
For the most part the only people wearing masks where I am are germaphobes and people that want to hide their identity.
The latter being the majority as there really is no other reason I can think of to wear a face diaper while driving alone, riding a bicycle in a very open space or walking in same.
Many criminals have been given a stay out of jail free card in the form of a 50 cent face covering for the last 2 years.
Since they stopped enforcing the law in NYC back in April, it was about 60/40 in the morning and the reverse in the afternoon. The Asians really love the power of the mask, hence why on SF it is higher.
