We already have a number on embedded processors and controllers in cars today, including systems responsible for critical operational parts of the car.

How autonomous systems will make anything different? Why do you believe people aren't currently hacking cars?

I don't intend to be critical at all, I believe this is a very interesting point too that should be discussed. (I hope to check the links on my interval).

It might make always on data connections near-mandatory (to get maps data, etc). At least in my car, the insecure embedded computers are air-gapped from the internet.

Part of the reason is that, in current ecosystem, companies will find ways in which self-driving requires being constantly on-line and connected to vendor's server. Off-line processing is not in fashion these days.

Off-line processing is absolutely in fashion with SDCs. Can't quickly react to a pedestrian jumping in front of your car when you have to bounce 12 1080p video streams to a AWS server.

Fashion or not, the speed of light is not going anywhere - latency can only be added, never removed. If the choice is "process locally or receive stale data", it's not actually a choice.
