Arthur C. Clarke was right. Today’s science fiction is tomorrow’s science fact.
The researchers didn’t find a wide-open door so much as the security employed by a 1920s speakeasy: once they learned the secret knock, the unidentified test car’s controls let them in no questions asked. The team sent fake warning messages from 40 meters away, and in another experiment, got the test car to flash a warning that a tire had lost all pressure while beaming the signal from another car as both drove 68 mph.
Because each sensor uses a unique ID tag, it was also possible to track specific vehicles, in a way that would be far less noticeable than roadside cameras.
The age of the carhacker has arrived.
