No. It's de facto impossible. If all I had to worry about was the software alone I would despair of ever correcting this in a reasonable period of time; to also have to overcome fundamental hardware challenges? Not a chance.

For a long time I've wondered what would prove to be Security-Pocalypse that finally convinces everybody that this is a real problem. This is not yet it. But if somebody takes one of these attacks and gets... "creative"... in those ways that aren't really that hard to come up with but I hate to actually spell out online (it's scary to think too hard about this... there's no possible way these vulns could be closed before a bad actor could... be very bad...)... that could become the moment the 21st century finally realized that secure code is no longer optional.

That will be one hell of a shakeup.

It is scary to think about because automated exploits could perhaps be scaled up and cause real mayhem. Hopefully it doesn't have to get that far before some elementary redesign of network architecture inside of vehicles. It's not rocket science. Just separate the safety critical network (which include brakes, steering, etc) from the non critical information and entertainment network.
