I'm really fond of the areas I've been where the only cars allowed on many streets are things like delivery and service vehicles. I would expect that that kind of environment is actually a net improvement to accessibility for people with disabilities. It's probably quite annoying for people who use wheelchairs to get around a lot of places without a car, simply because the sidewalks are so frequently blocked off by people who've parked their cars across the sidewalk. There's one man in my neighborhood who frequently has to go out in the street to get around those sorts of obstructions, and is then stuck out in the middle of the road until he can get to the next wheelchair ramp in order to get back on the sidewalk. Limiting private car usage would admittedly only remove a portion of the sources of obstruction, but it would get rid of essentially all of the safety hazard that he has to take on in order to get around them. And, especially now that cars are going electric and getting quieter and quieter, I would guess that restricting unnecessary car usage could be a big boon for blind people who want to be able to leave the house without a chaperone. I had one acquaintance who would essentially Uber everywhere - at great expense to herself - because she just didn't feel safe even trying to cross the street. (Heck, I'm sighted, and sometimes _I_ don't feel safe trying to cross the street, especially later in the evening when a sizable portion of drivers are intoxicated and really are not watching for pedestrians.)
