Honestly I think the cars all looking exactly the same, and in most cases actually BEING the same, is a big factor. There used to be 5 or 6 chassis builders plus the occasional guys like Plazek or Heotzler or Kisacky that built something different. Bodies were different, you had a choice of tire brands and compounds, fuel, etc…. Now you have almost exclusively Bicknell cars in any given race. 🤷🏼♂️
