Johnny Blackbird finally drove the car to a slum in the West District.
Yes, there are slums in the West District too.
The West District was the latest to be developed. Although it is now outwardly declared to be a gathering area for major institutions, arts organizations, and museums,
the Kingdom's financial resources are limited, making it impossible to completely develop the entire West District, thus leaving quite a few vacant areas.
These places may have originally gathered people, or they may have been occupied by people later on.
For example, the western part of the West District, which is now overrun by gangs, was initially just a place where the lower class gathered. It only became what it is now with the infiltration of western gangs.
The place where Johnny Blackbird took Ethan and the others shows more of a central region flavor.
Or, to be more blunt, this is a gathering area for the natives.
