There is a GS Cars Turning Curves object in which one can pick between two “driving styles”, 1 and 2. The object was originally German, and in the script they call that Fahrweise. Style 2 gives a tighter curve —if I had to guess I would say the vehicle comes to a stop, turns the wheels, and then starts. I've Googled with no success. Anybody knows?
This one is a much simpler version of that, a Graphisoft object, originally in German. I am sure the Driving Styles/Fahrweise must refer to some DIN standard or whatever, but I just can't find a description.
