While fully-autonomous vehicles will take years to come into fruition, we are making improvements to the driving experience happen sooner. We do not let perfect get in the way of better. Our technology is designed to be released incrementally: So long as it improves the driving experience, we'll ship.
Our mission necessitates scalability in every product we create. It is not enough to make a product that only works for certain neighborhoods or one which is too cost-prohibitive to bring self-driving vehicles to mass production.
We will keep iterating until our products are the backbone for full "Level 5" autonomy.
