More evidence that cars are vulnerable to hackers

Last May a study was released that suggested that the computers in cars are vulnerable to hackers. A new study confirms that this is a potential problem. From ABC News:

The new study, along with a similar one from May, suggests looming dangers: People within a vehicle could be tracked using the wireless signals, and they could potentially could be harmed if malevolent hackers learn to exploit or invade a vehicle's control systems from a distance.

"Our research shows that there are multiple risks," says Marco Gruteser, associate professor of electrical and computer engineering at Rutgers University. "Privacy is a problem since every car has these unique fingerprints from tire pressure, and that makes it possible to track movements. But this vulnerability can lead to something more serious."
