Why in the world would/should a car in London be relying on a cloud computer in SF to tell it how to make real-time decisions...?

Most of the teleoperation companies at the moment. As far as I know. Worse still many are intending to gang onto the primary cellular infrastructure to perform the function. Which makes everything worse.

If you are asking this question you are clearly more informed than the sales rep asking about being on the edge.

The point wasn't that a car would ever do this. The point is that it would be absolutely ridiculous to do real time computation with such a high latency. Unless your question is rhetorical, there is no answer except "you would not do that"

Some people out there for sure have no idea that the cloud is still bound by the constraints of physics and spacetime and that there is latency based on how close your servers are.

One time, I got a telemarketing call from someone selling satellite TV or something like that. I kept him on the line some time, asking all sorts of enthusiastic questions about his amazing service. I then proceeded to ask him how high up his satellites were, and if they could be giving God cancer. He (obviously) did not have a good answer. I then disappointedly told him that I was going to have to run his setup by my wife, as she made the religious decisions.

This seems like that, modulo Poe's law.
