So you don't understand or know anything about the technology ....and that has led you to conclude that it must be media hype and Elon Musk jacking up his stock price?
I remember back in the 80's people not understanding emerging computer technology and not able to envision computers in every home, a phone in your hand etc missing out on Apple, Microsoft, Intel and other great tech companies and their stock. People would blah blah blah how it will never happen computers are too expensive too big, a phone in your hand that's Star Trek futuristic nonsense etc. Thankfully people like Jobs and Gates were able to see the future and savvy investors were able to profit. Musk and Huang are building the future here and now along with every other car manufacturer.
I suggest everyone to do their own homework and read up. Lots of myopic misinformed responses that show a lack of understanding of the technology jumping to false conclusions.
Lidar sensors, Radar sensors, camera, gps (which is accurate to 2-3 meters) powered by Drive PX 2 installed on the car not on roads or highways. It works today right now in any weather and road conditions, snow, rain, fog.

This was last year. CES 2017 begins January 4. Expect to see some incredible technology from Nvidia. I suggest viewing the presentation it will be available on the Nvidia website.
