I'll add one. Did you know that if you're cruising down the highway and need to accelerate hard, punch the throttle and click the downshift paddle - the car will shift down to the optimal gear for accelerating. For example, it could shift from 7th to 4th in one shift - no need to click the paddle 3 times.
