Nothing crazy about it. TPU-like stuff is ~10x the energy efficiency of GPUs and several times the speed. When you're spending megawatt-hours and days to train a single model, it adds up in both real and opportunity costs.
Also, Google TPU TOS prohibits the use of TPUs for stuff that competes with Google (and I'm assuming with other companies under Alphabet umbrella), at Google's sole determination. Not that it would be a good idea to upload Tesla's proprietary data into Google Cloud even if it did not. Cloud, after all, is just somebody else's computer.
