I notice nobody has commented on the fact that the driver should've reacted to the deer. It's not Tesla's responsibility to emergency brake, even if that is a feature in the system. Drivers are responsible for their vehicle's movements at the end of the day.
True but if Tesla keeps acting like they're on the verge of an unsupervised, steering wheel-free system...this is more evidence that they're not. I doubt we'll see a cybercab with no controls for the next 10 years if the current tech is still ignoring large, highly predictable objects in the road.
