I believe it's 'only' a one-race ban when you go over the limit of 12 points; not sure whether there are some more severe penalties for repeat offenders.
It's a single race ban and the points expire after 12 months, not even 12 or so races, meaning summer and winter breaks pretty much guarantee that nobody ever gets penalized.
There are 22 races this season, somebody should tell him he is going to earn a race ban at this rate. But Im personally betting Papa Stroll doesnt let that ban happen at all. Lance basically got a light tap on the hand with a paper fan for destroying somebody elses race.
