j01: Son of Sleazy is an early test-bed used to test traffic and pedestrians. It has textures and objects reused from default cities. However, unlike the default Midtown Madness 2 cities with traffic and pedestrians made by Angel Studios, this one doesn't have cops available. The hudmap was reused from an early beta version of San Francisco (s_sfmap_f.tex). You can still use it, with the help of MM2 Revisited V5 and later, although it can be buggy at times and sometimes crashes the game. This city is actually part of New York City, which was later included in Midnight Club: Street Racing for the PlayStation 2, made by Angel Studios. In said game, files for this city can be found in the August 2000 build's game files.
