Can self-driving cars be framed as robots?

An electric car would have no issue sustaining this level of power; a gas-powered car doubly-so.

Autonomous vehicles are indeed robots, but they have power constraints (that Thor can reasonably fit within). Most industrial robots aren't meaningfully power constrained though.

It was a bit of a culture shock the first time I was involved with industrial robots because of how much power constraints had impacted the design of previous systems I worked on.
