A few years ago, my nephew bought a Cadillac and outfitted it with a self-driving kit. He flew from CA to NC, installed his self-driving system and had the car drive 97% of the miles home. At the time, it was the cheapest car that had the necessary controls. Now he also has a... Nissan Leaf plug-in hybrid I thin? A cheaper car that he has also kitted out to be self-driving on easy roads.
He also races cars in the spec Miata class. All in all, he's a fan of the Caddy. Says it's a nice car.
