Dash: Tweet-tastic

Saw the following social media post this morning from the JEGs Performance account: So, I googled my symptoms and it says I need more horsepower.

C Main: A Different World

Media is very different today than it was when this reporter got his start under the tutelage of Chris Economaki in 1991. Digital and social media rule and the NHRA has made a big step to cater to Content Creators.

The NHRA has created the Cornwell Tools Burnout Box Content Creator Zone and is inviting social media influencers with 25,000 or more followers on any platform to experience this VIP opportunity, helping NHRA reach new audiences.

Thinking of the folks who may visit the Creator Zone, reminds us of one of Economakis favorite sayings He/she doesnt know which way the cars run.

B Main: Yellow Flag Endings

Through most of my time following NASCAR racing, it was common for races to end under yellow flags with leaders often allowed to race to the yellow flag. But some years ago, NASCAR initiated Overtime and the green-white-checkered finish of which it seems that every other race ends in that fashion.

But it created a standard whereby more often than not if a crash happened, the yellow flag appeared and the leaders did not race back to the yellow flag. It was understood.

But through two weekends this year, NASCARs officiating in these situations has been far from consistent with nearly identical situations handled in different ways.

Its led to justified criticism from NASCAR fans and confusion among competitors.

During a time when, Major League Baseball is experimenting with digital umpires calling balls and strikes and the NFL is preparing to digitally measure down and distance, is there technology out there to make NASCARs officiating more consistent in these cases?

One would think that drivers in major racing series know how to contact one another, but as Austin Cindric revealed this week, thats not usually the case.

Cindric was in conflict with Kyle Larson following a late-race crash Sunday at Atlanta Motor Speedway and left his business card to Hendrick Motorsports Vice President of Competition Jeff Andrews in the garage area following the race and asked to have Kyle call him.

I saw Jeff Andrews and Chad Knaus standing over by the 24 hauler, so I figured that was a good way of ensuring that I would get my conversation and that would be a lot healthier than just showing up at the race track, Cindric said. Sometimes guys will reach out to you and sometimes guys wont. I dont have a super close relationship with Kyle by any means, so its not like hes got my number. I guess that was my way of saying, Hey, we really need to talk about this, in a way that was gonna be not emotional for me because at the time I was pretty frustrated.

Cindric confirmed he had with Larson on Monday with the two discussing Sundays incident and moving on from it.
