Traffic jam computer style

Toyota's Prius is a wonderful car. It's the wave of the future but, as software becomes a more integral part of a car, we're going to see more problems like this.

Attempts to hack the Prius have proved unsuccessful thus far but with the way exploit code goes in 50 years it won't be botnets taking over your PC that cause headaches, but possibly joyriders taking your car for a spin remotely.

Nevertheless don't let this put you off a Prius. If the ex-head of the CIA drives one for national security we should all take note.
