You're off to a very good start already with that attitude towards it, remember, it looks really bad to make a mistake, but even worse when you get angry and shout at people. Good going. Resist the red mist.
Also, another little tip that probably will not help since you probably already do it, but watch some real life motorsports, and replicate what they do. Even when it comes down to recovering your car from off the track, real life drivers will wait until its safe to rejoin, in a certain technique which is a combination of getting back on the road but staying off line until back up to speed, putting the car on parts of the track where even if 2 cars come by, they have room etc etc etc. You can learn from the real guys.
