On the points scoring, the points for each car are effectively halved. So whilst you do get points for both cars, its only worth similar points as one driver.
The points are mainly based on qualifying and race results, but the other one is positions gained. If you start 15th and finish 10th, you get 20 points (four points for each position). I find this rule favours cars that qualify down the back always.
