Hackers can use smart keys to steal cars

From a report at the link below:

Modern smart keys use radio frequencies to let drivers unlock and start a vehicle without fumbling with a key fob.

Now European researchers have found such systems can be hacked, letting thieves easily steal your car.

Seems like there should be a simple fix. How about a shielded bag to go over the key fob?

One commenter suggested with tongue-in-cheek that driving an old stick-shift car would completely throw off car thieves.

One look at a clutch pedal and a three-in-the tree gear shift lever and they wouldn't have a clue.
