This is exactly what I needed! You included pretty much all of my most-used UI apps into one.
Do you plan on using the streetcredits to give performance feedback to the AI? It definitely seems that the current AI don't really consider variations in the handling characteristics of vehicles (e.g. putting a heavy load in the back of the D-series will result in the AI braking too late). A scoring system for the AI's driving is a great idea!
