Tesla's bold proclamation was "No LIDAR!" They're at 8 cameras per vehicle, used a powerful Nvidia graphics processor as a place holder while they designed their own silicon, and continually tweeked their design until they had data to show that the radar was mostly redundant and could be removed from the 3 and Y.
"Mostly redundant"! If radar's not totally redundant, it needs to be kept if there's any hope of truly safe autonomous driving. Tesla used to promote how cool its radar is because it can detect vehicles ahead of the one immediately ahead by bouncing radar off the road under the vehicle ahead. That gave the collision avoidance system an earlier alert that traffic ahead was decelerating or stopped. Radar could also detect vehicles and obstacles ahead that are obscured by fog or darkness. These significant advantages of radar are almost certainly lost with an all-vision system that cannot see through the vehicle ahead, fog, or darkness.
Certainly Tesla is aware of these radar advantages and apparently thinks that an all-vision system can overcome these advantages. I'll be paying close attention to how this seemingly impossible feat is accomplished.
