Wow , i´m already drooling in anticipation 
I´ve managed spline based and AI driven vehicles in UDK, and can get away with murder pretty much. In Blueprints, however, I´ve got no idea as to how to approach stuff like, stoping a car for a given amount of time (say on a red light), give way etc… I´ve yet to pick up the language for AI Vehicles, that´s why your tutorials are invaluable!! Thanks again for sharing your knowledge.
