Tesla sold a $3000 "full self-driving hardware" upgrade for a while, and now advertises all cars with the same, while suggesting that the software update to enable it is just around the corner. If they admit that radar + optical cameras won't be good enough for full self driving, there may be a lot of refunds to process. From first principles, just optical cameras should be enough - humans can do it. But the software to make it work could be general AI level complex. Personally I think LIDAR self-driving will be available in less than 5 years, but optical may take 30 years. And the company who would be most capable of developing optical self-driving AI is Google, the fact that they are sticking to LIDAR is a good indication of the complexity of optical.
