"As cars get more connected, the industry is trying to stay ahead of multiplying threats"<p>This is actually not a hard problem. The convenience part of a car, infotainment systems can be connected to the Internet. The safety parts of the car: the wheel, the breaks, etc should not and there should be no connectivity between the two.
And we certainly ony allow OTA updates of the infotainment system. The rest should be done at a dealership. Inconvenient, but I certainly don't want my breaks susceptible to hacking.
