As long as you do two laps, you don't get any penalty for quitting a race early or not finsihing it for whatever reason.

You only get a penalty (I think a two day suspension) when you sign up for a race but don't attend the race. You have to do at least two laps in a race or otherwise you'll get that penalty.

In case your computer crashes before the race starts and you miss the start, you can join the race later, do two laps and quit again to avoid getting a penalty.

Your result will be bad and you'll lose rating points, but you won't get a penalty for it.
