Apparently, the Prius can be hacked and controlled remotely:
Hackers plan to offer blueprint for taking over Prius, Escape
Two well-known computer software hackers plan to publicly release this week a veritable how-to guide for driving two widely owned automobiles haywire.
According to Reuters, Charlie Miller and Chris Valasek will release the findings -- as well as related software -- at the Def Con hacking convention in Las Vegas, showing how to manipulate a Toyota Prius and Ford Escape.
The research, conducted with the aid of a grant from the U.S. government, can alternately force a Prius to brake at 80 mph, veer quickly and dramatically, or accelerate, all without the driver’s prompting.
The two hackers have also reportedly figured out a way to disable a Ford Escape’s brakes while the vehicle is traveling at “very low speeds,” no matter how hard the driver attempts to stop.
In both cases, the would-be hacker would have to be inside the car in order to tamper with its computer, according to Reuters.
