Lessons learned:
1. hit the breaks to prevent the car from rolling back on the track. It is very dangerous and unpredictable for other drivers to have a car shoot across the track
2. Qualifying is not a race. I don't understand why there are so many bulks of cars together sometimes even racing each other. With so many cars at different speeds close together the lap is wasted anyway - why not slow down, let the others go, relax the tires - and get a free, fast lap? This is way more effective, not speak of the risks (see above).
