I think the part that Elon, and the engineer, are trying to express that you are looking past is "A dot product with some memory attached" is what they need to do low latency image inference on the camera data.

They don't need a multipurpose CPU/GPU, they have a single well defined task that dominates their compute needs. They built a chip to do this that is cost and power effective, and redundant for safety.

Right, but Nokia's 5G backhual infrastructure is far more capable of doing Mobile backhaul than a GPU, you don't get the head of Nokia standing up in a press conference telling everyone his team has designed the best chip in the world.
