Software updates for cars should be rare, with the infotainment systems physically isolated from the rest of the car (aside from constant/switched power). And if it needs updates for whatever reason (eg a recall), they should be done at a dealership - not over the air.

Bricking a car with an over-the-air software update is stupid and unacceptable behavior. Stuff like this is why I'm actually kind of happy to be driving a 20 year old car still.
