I have already completed and I have added more cars I'm up to 115,000 the system works great but it is starting to overload itself. I will have to probably clean up the code and chop out areas to stop the program from over loading itself.

The system also only uses a fixed map which means it doesn't know what to do if I throw in a new map so either The system needs to be able to detect roads or will need a detailed map of the entire world from main roads to secondary roads.

The last thing I need to work on is highways, the cars seem to freeze up when on the highway because they are confused on what they have to do when they are surrounded by cars so that will be another thing I'll work on before I can fully finish.
