A flaw buried deep in the hearts of all modern cars allows an attacker with local or even remote access to a vehicle to shut down various components, including safety systems such as airbags, brakes, parking sensors, and others.
The vulnerability affects the CAN (Controller Area Network) protocol that's deployed in modern cars and used to manage communications between a vehicle's internal components.
The flaw was discovered by a collaborative effort of Politecnico di Milano, Linklayer Labs, and Trend Micro's Forward-looking Threat Research (FTR) team.
Researchers say this flaw is not a vulnerability in the classic meaning of the word. This is because the flaw is more of a CAN standard design choice that makes it unpatchable.
Patching the issue means changing how the CAN standard works at its lowest levels. Researchers say car manufacturers can only mitigate the vulnerability via specific network countermeasures, but cannot eliminate it entirely.
"To eliminate the risk entirely, an updated CAN standard should be proposed, adopted, and implemented," researchers say. "Realistically, it would take an entire generation of vehicles for such a vulnerability to be resolved, not just a recall or an OTA (on-the-air) upgrade."
[...] The Department of Homeland Security's ICS-CERT has issued an alert regarding this flaw, albeit there is little to be done on the side of car makers.
"The only current recommendation for protecting against this exploit is to limit access to input ports (specifically OBD-II) on automobiles," said ICS-CERT experts in an alert released last month.
[...] The research was presented last month at the DIMVA conference in Bonn, Germany. The technical paper detailing the flaw in depth is available here and here. A YouTube video recorded by Trend Micro researcher Federico Maggi is available.

You're a fucking idiot. C&D tested this stuff as I showed. I remember this incident well; this guy wasn't in any danger, he was making the whole thing up so he could sue Toyota.
The brakes work fine in an incident like that; you step on them and stop the car. Priuses do not have a lot of power. And his lies about not being able to turn off the car are bullshit too; you just press and hold the start button.
Give it up. You have no fucking clue what you're talking about, and it becomes ever more apparent with each of your pathetic replies.

You're a childish ninny. But that's ok, you have the right to be wrong.
