This is a cool looking game. Genki is working on Maximum Chase for a Jap. release, but I hope that someone brings it stateside. Here’s the story according to Gamespot:

(The Player assumes) the role of a Los Angeles police inspector named Rick. One day, a mysterious beautiful girl suddenly enters his car asking for his help. The game makes use of both car chases and shooter elements as players protect the girl from the armed gangsters who are after her.

Looks a bit like Driver, with more varied terrain and locations. Screenies are available at Gamespot here and here.
