Those tend to be areas where women have little education
By the 1960s, the USSR had more women engineers than the rest of the planet combined, and some 45% of the PhDs in chemistry in the 1970s were awarded to women. Mistakes were made in the USSR, for sure, but equal access to education between women and men was not one of them.
After visiting Russia some time ago and comparing old pictures, a lot of the trees were cut simply to make parking spots. Most people didn't own a car in the USSR because public transit and walk ability were prioritized, and so these areas weren't designed with parking in mind. When the Soviet Union was antidemocratically dissolved, public transit was gutted and cars were heavily publicized, so most families who could afford it ended up buying some old car, and they needed parking spots.
