We tried. Nintendo won’t license it to us.— Elon Musk (@elonmusk) November 29, 2018
For those who don't know, Tesla cars have very big navigational screens in their dash that control a very large portion of the car. Some people want to see Tesla put some games on those screens, According to Elon Musk, the Tesla gang was interested in the idea as well. They went as far as to contact Nintendo in order to use the Mario Kart brand, but Nintendo shot them down. With Nintendo constantly worried about player safety, it's not hard to imagine why they declined this offer.
