Seriously? You're illustrating the point here. On low tech cars, an attacker has to hack the cars one-at-a-time. They could endanger one car load of people with each "job".
With high-tech cars, an attacker could hack every car of the same model. With thousands of Teslas on the road, I think it merits a higher concern than somebody with side cutters.
I thought it was obvious. Next time I'll let it go unsaid..
yeah but the state police can examine a crash after the fact to determine a brake line was cut.
even if the software survives a high-speed crash, it's possible for the surreptitiously placed modification to erase itself as its final act. additionally, the surreptitiously placed modification can wait for weeks or months, giving the attacker time to build a cover story or misdirect or accomplish any number of other goals.
