nascar has decided to switch to a new rim that doesn't take lug nuts, just a center fastener.

There's no point in me writing about it, I'm not into nascar and the writer at ESPN.com already did a fantastic article on it.

https://www.espn.com/racing/nascar/story/_/id/28824606/changing-tires-big-shifts-nascar-2021  pointing out that this will have a lot of side effects... even lug nut mascots will have to come to terms with this change, because a mascot based on a piece of hardware that no longer is in the sport? Doesn't make much sense.

Read that for a good piece of writing though... it's worth it.
