Hi !
You can do the camera animation somehow similar, with the default navigation via the 'alt' key and the left, middle and right mouse button. That navigation is shown in my first tutorial video.
Takes about 15 minutes to 'acclimate' to it, but once it's in, it's pretty handy. Though, the camera flights will not be as fluid as with a 3d mouse. [ Cheapest model of those 3d mice is about 99$ or so, which would do the job just fine. ]
Also very important for the navigation is the 'f' key and the 'a' key to frame objects. Framing sets the camera's focal point around which the camera spins.
The cars themselves cannot be animated in CE. So they can't drive around .. The cars are just created as a part of the Street Models. But showing some cars on the Models gives the impression of traffic. 🙂
Let me know if you have more questions .. !
