In my opinion, most of the above image would be good for roadside parking( Tag:parking=street_side).
Because the road seems to be mainly for the purpose of traffic… (Excluding the upper left corner)
In the image below, the left, right, and top are used only for parking purposes, so it would be nice to designate them as parking lots, and designate the rest as curbside parking( Tag:parking=street_side).
Even though the streets around the parking area are used for vehicular traffic, it’s probably safe to consider them all as parking lots because of the large number of cars that can be parked there.(It’s too large to be a simple curbside parking lot.)
It seems to be a matter of which attribute you value more.
