Tesla's Twitter account says that track mode is exclusive to P3D+. So what if someone wanted to put that $5000 toward their own track setup, rather than buy Tesla's? Elon said himself that a staggered wheel setup would probably help get the 0-60 time down to low 3's. All of the performance upgrades can be added after the fact without getting too invasive. I could add everything in my garage, save for the software update. Also, it says "features exclusive to performance" on the base P3D. The only defined software difference was the top speed. This led me to believe that track mode would be offered on the P3D and the P3D+. It's frustrating that they would split the performance model 3's into 2 sub groups based essentially on tires and brakes. Track mode was for tinkering and modding to get the best performance, but only if you buy their setup? It just seems like a dumb spot to draw the line to me. I'm spending over $70,000 on a performance model with the intention of building my own track setup over time, but I don't get track mode because I didn't buy their tires and brakes. Track mode should be exclusive to P3D, not the performance tire package.
