Quick peek at the thing I've been messing around with.

Adding more doodads to interact with during a rampage as well as some rudimentary ambient traffic. Right now doodads are limited to trees and barriers on the overpasses, but there's plans for more like parked cars and rooftop objects (HVAC, telecom towers, water tanks, etc).

The buildings also got slimmed down so there's small pathways between them, and I can stick some more doodads in there like dumpsters or billboards.
