Georgia Institute of Technology (Georgia Tech) researchers have determined that hackers could target Internet-connected cars and freeze traffic, creating extremely disruptive gridlock in major cities.

The researchers ran simulations of hacking Internet-connected cars in Manhattan, and found that randomly stalling 20% of cars during rush hour would result in total traffic freeze.

Hacking just 10% of cars at rush hour would prevent emergency vehicles from expediently moving through traffic; the same would happen with a 20% hack during intermediate daytime traffic.

One possible solution could be to split up the digital network influencing the cars, to make it too difficult to access too many cars through a single network, said Georgia Tech's Skanda Vivek.
