The Polizia and Taxi are perfect for the new map, they fit in perfectly, well done, I use them a lot.
Only thing bothering me with the Polizia is the lightbar, is there no way to disable the red traffic signal or create one with international signals?
Now there is no large map based off Germany yet, but the 'Green Polizei' is pretty much outdated by now, most cars are blue and yellow since a couple of years.
Maybe you could make a new 'Polizei Variant', based off the Bavarian police some day, they look quite nice.
But who knows if we ever will get a German map besides the ETK Driving Center ;)
