How to Make Grippier Racetracks Using Spy Technology

If PJ1 TrackBite isn’t the Solution, What is? Dale Earnhardt, Jr. suggested tracks stop using PJ1 Trackbite because it didn’t work well in Charlotte last weekend. He called for additional research to understand how the substance affects the track before continuing to use it. A couple of drivers expressed similar…

Or something similar.

I’m going to look at this in two ways. People often confuse how much energy is used with how efficiently energy is used. One way to cut back on energy usage is to use less energy, but it’s also possible to use less energy by using the energy more efficiently.

Daytona is an enormous, sweeping track. Two-and-a-half miles, 31-degree banking and corner radii of a thousand feet. The infield by itself is 180 acres. If you’ve ever been there (or Talladega), it really does take your breath away when you first enter.
