This should be made illegal. It’s a massive national security threat. Imagine on the eve of a war, instead of Jeep 4xes, it’s every recent Ford or Toyota or GM car, and instead of a software update that can be rolled back, it wipes the flash completely, or reprograms the ECU to damage the engine or disable the brakes on the highway or something else to cause accidents.
You assume that it will be a foreign enemy and not your own government bricking your car on the eve of revolution.
