Irrelevant to this issue - the devices didn’t get bricked over the air, but rather they have a “calibration” time lock which must be reset at a service center and the service centers are ransomwared.

That's an extremely attractive attack surface. How about we just have keys to turn on the engine?

Disabling all of them would have silly consequences, and wouldn't be compatible with other safety regulations.

I feel like a lot of you are commenting without reading the article. Vehicles are not being remotely disabled.

The computer systems which perform the calibration on the device (usually done at a mechanic or auto electrician) are under attack. The vehicle will get locked out of this calibration is not performed monthly. There is no remote attack on the vehicle.
