How to play Vroom (ENG)

About Vroom, from BoardGameGeek:

Vroom is a cooperative racing game. Evaluate your speed, move your car without board nor reference points and try to cross the finish line in the correct order. Draw a Speed card and move your car on your made up circuit. With values between 1 and 7, the cards won't make you move with consistency and you'll need to evaluate the distance your car will move; with no board and tiles to guide you. Only your car movement will give a clue about the card you drew. At the end of the fifth round, everyone must be ordered in correlation with the sum of the 5 Speed cards they drew. Events and other optional modules will shake up your strategies a little once you get the hang of it: Jump stunts, landslides, weather and more...
