It's safe to say that Tesla's self-driving efforts haven't gone smoothly. It took the better part of a year for Smart Summon to arrive, and there's not much time left to fulfill goals of full self-driving (on city streets) before the end of 2019. The automaker might speed its progress soon enough, though. CNBC claims that Tesla is buying the computer vision startup DeepScale. The company specializes in making accurate AI vision technology practical for the low-power, low-memory chips often found in cars.
