Tip: Do not, repeat, do not, brake while in the midst of a turn, particularly when driving older automobiles. The EA version of an antique Porsche has a tendency, and probably rightly so, to seriously rock your world if you do, sending you into a drift from which you may not recover. Instead, brake early, turn smoothly, and accelerate on the exit.
Tip: There's no better way of ridding oneself of an annoying police officer than by nudging him into a passing motorist or solid roadside object.
Tip: Alternate routes are not always shortcuts. If you find yourself consistently slow on a given course, check out all the routes available to you before resorting to a different setup.
Tip: Go with the "front bumper" camera for the best results. Here, the program doesn't have to pump out cockpit and driver animations, so the frame rate is generally faster. Also, you get a better sense of the speed at which you are traveling, so you'll be better prepared to slow down for upcoming turns.
Tip: Torque rules. If you find yourself in a section where you can use a higher gear with lower RPM or a lower gear with high revs, go with the latter every time.
