Who actually does these? Car or bike? Where? How much? When I read the specs on new sporty/sports cars/bikes, they have electronics for track modes. I thought to myself, who actually does them? What percentage of buyers go to the track that would warrant such a feature? I thought it was just an ego button on the dash, i.e., hey, my car can go fast on the track and yours can't A few years ago my buddy who goes out to Willow Springs to do track days on his CBR, wanted to throw my Hawk in his pickup and take me with him. IIRC, it was about $300 for the day, and he said I would need new tires afterwards. His track bike was a dedicated machine, he also had another street bike. Since my bike was my only transportation at the time, I declined.
