The answer is yes given the extensive processor demands, i.e. the enormity of data, of the neural network system being implemented
by Tesla for AP without using LIDAR. Tesla most likely will switch to the later Nvidia processor when available as system demands approach
AP 5. The Nvidia stock was a great buy at about $80 -$90 (now $245) when Tesla switched from Mobileye.
It looks like you made a good call on this lorenfb:
Tesla could have to offer computer retrofits to all Autopilot 2.0 and 2.5 cars by the end of next year.

Now it looks like Tesla might have to also offer computer retrofits for Autopilot 2.5 cars.

Elon Musk wrote:In order for that to be in place, we have to obviously sell full autonomy and we’re making really good progress on that front. I believe that the vehicles that we are currently producing are capable of full autonomy with the only thing that maybe is probably needed is a computer upgrade to have more processing power for the vision neural net. But that’s a plug-in replacement, a thing that can be done quite easily.
Tesla indeed made the onboard Autopilot computer easily swappable if they need to upgrade, but even if the task to replace it is somewhat easy, it can still add up to quite a significant retrofit program for the automaker.
Thanks for the feedback and update. It''s not easy to forecast present processor requirements based on future software developments.
