A lot of people talk about the "Does it have enough sensors for Full Self Drive?" but my question would also be: Does it have the Compute?

As vehicles get closer and closer to full self drive the compute requirements have shot up, that's because a lot of the building blocks are just adding more machine learning models, pattern recognizers, and a more complete picture of the world. It is all well and good having a dozen sensors, if you can process their input.

A lot of the key cycles cannot be offloaded to The Cloud because of the tolerances (e.g. sub-second query/response for safety). One university project I happen to know of had $20K worth of compute sitting in the trunk. That will obviously come down as it is optimized but a vehicle sold in early 2018 isn't evergreen.
