I've roadraced karts for almost 30 years all around the country. Been the race director several times. I've spent time in flaggers stations watching. I am just now going to dip my feet into a vintage supervee and find this thread interesting. We suffer the same issues in karting. No respect for the yellow flags and it just seems to get worse.
I can't tell you how many times Ive stood in the drivers meetings and told them it has to stop. I think if everyone would have to go to a crash scene to do an insurance report (I've seen dead and injured drivers) they would change their tune. I feel the problem lies in policing. Nobody wants to be the bad guy. Corner workers are spread thin and or inexperienced. Things don't get called in, rd's are afraid to make the call. Nobody wants to piss off the customer. Drivers continually take advantage of yellow zones to make up ground.
My take...until it's policed and drivers are made examples of it will never change. In fact, it will continue to grow worse. Will it piss someone off? Sure it will. Might there be a protest? Probably. Will they never come back? Maybe, but if they are unsafe is it a loss?
An ultimatum must be given across our sport. Speed or pass under caution and you will be black flagged. No exceptions. Make the penalties stiff and let them know that this is your only warning. Word travels fast these days. Start applying penalties and people will hear and maybe think twice. Hard ass? Yup, but I see no other way to get things to change. It's for the safety of all. Especially the corner workers. Remember that without them we don't race.
I'll step off the soap box now. Thank you
