Microscopic traffic simulation is a difficult problem to solve, it's not car movement, it's driver's behaviour. The model has to be good enough to reproduce the current situation and, what is the most important part, be able to test realistically future scenarios. In any case the new SimCity looks fantastic, maybe we can exchange our simulation model (Aimsun) for their graphic engine :)
