No way a self driving car can rely on Internet access to "perform basic driving functions". Lag and connection failures would kill people.

They might need Internet access for updates, in which case, there should be a physical switch that connects the net and disables the engine.

An air gap is hardly a solution for traffic information the route planner HAS to talk to the computer responsible for getting from A to B. In the same way that firewalls are no longer particularly relevant, air gaps appear to be flawed now too, the only way to solve any security issue is better code quality..

It's not perfect, but an air gap can help reduce the attack surface and interval.

Better code quality is important too, of course.

I agree with cameldrv that it's going to be a challenge.
