Im sure you're probably right but maybe in this case as an optional extra, albeit very expensive, even if it's just for the ultimate track toy switch on the hyper performance cars that owners love to take to track days or maybe they'd just like to have bragging rights over their friends.
And also another excuse and opportunity for the manufacturer to make a lot of money on the request of the rich consumer as they tick the option extra box and at the end of the day the more it's talked about this year (and I'm sure it will be talked about a lot), the more the seed is set for it to be requested if it's seen to be successful on track.
