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 MM2 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. You can still use it, with the help of MM2 Revisited V5, although it can be buggy at times and sometimes crashes the game. This city is actually part of New York City, which was later released in Midnight Club: Street Racing PlayStation 2 game made by Angel Studios.
