Maybe time to start parking people for races after X incident points? Or X incident point limit per 2-3 races, and if you hit that you're done for the next one? It seems to me it's the same few people causing 95% of the cautions every single time. Time to crack down on it. Not gonna lie, I'm still a bit salty for getting a yellow card racing someone, and when someone spins their 40 lap old tires and kills half the field they get away with it...
We tightened the penalties regarding yellow flags compared to last season, and introduced the possibility to loose the seat in the series and drop down the revived offspring series. Those penalties already caught drivers. Maybe it has to be tightened more? We will see how the season develops, as some more drivers are on the verge to get caught out.
I'm under the impression that some drivers don't care about this (or may not be aware?). Behaviour on track eventually has to change. Thomas pointed that out beautifully.
