Tesla's auto pilot isn't at all comparable to what Google are doing. It essentially the same as the adaptive cruse control (cruse control that adjusts to traffic in front) and lane assist (auto stearing to stay in lane) you can get from most other car manufactures as an option.
That's not to say that tesla isn't developing full automation it's just that what they sell now is just clever branding on something you can get elsewhere.
