I want to see them do this on a car going down the road next to me through the wireless connection.

The article notes that the wifi problem has already been demonstrated, these guys are showing what happens after control has been compromised.

The comment about worrying about a guy with a laptop is silly. While a direct wifi connection to your car's computer would not leave traces, a Raspberry Pi computer + wifi could be connected to the data port and tucked under your dash and you'd likely never notice. And since the car companies are mostly worried about wifi penetration, the data port is the current weak spot.

The third law of the Ten Immutable Laws of Computer Security is:

If I can get physical access to your computer, it's no longer YOUR computer.

Now it applies to vehicles, too.
