I just purchased a Model 3 Tesla, and this car make me smile everyday. I takes me back to teenage years when driving was fun and my parents could send me on errands, because there was Joy in driving.
I have a great deal on fun showing the self driving off to others, not to mention just the fun features like driving on Mars. I just got my first software update, without going to a dealer, and the car added the new feature of attaching driver profiles to your keys.
Ford would never let you drive on Mars and I strongly believe GM would never just add a nice feature like driver profile to your key without a major charge and a long wait at a dealers service center.
