firstly, this all starts with junior series that don't and won't penalise drivers for doing stupid moves that break the rules. most, if not all series do this. you will struggle to find a driver who has not had someone get away with driving into them. equally you won't find anyone who hasn't said 'but the stewards didn't penalise me so it's ok'
if they arent penalised and suffer as a result of these stupid moves, they'll continue to do it. f1 hosted series are a bit better, even if they hand out meaningless penalties anyway. this becomes obvious when you get a rookie f1 driver sticking his elbows out to get past someone in a f1 car and making a move that requires the innocent party to make an evasive move to avoid an accident. cue drama, and quite rightly too.
you can substitute track limits issues in the above too. scores of young drivers are unable to set a couple of consecutive fast laps without exceeding track limits because in the absence of consequences the skill to walk the fine line of 100% hasn't been developed.
it's great to see someone come in and ruffle some old farts feathers but be under no illusion about the strict legality of the crap he's pulling here.
