Keen Labs, widely regarded as one of the most technically ingenious cybersecurity research groups in the world, developed two kinds of attack to mess with the Tesla autopilot's lane-recognition tech.

First, the researchers sought to make alterations to lane markings, first by adding a large number of patches to the line to make it appear blurred. It worked, but as the patches looked much too conspicuous, the Keen hackers decided that it'd be too difficult to carry out in the real world.

So the researchers tried to create a "fake lane." They discovered that Tesla's autopilot would detect a lane where there were just three inconspicuous tiny squares strategically placed on the road. When they left small stickers at an intersection, the hackers believed they would trick the Tesla into thinking the patches marked out the continuation of the right lane. On a test track, their theory was proved correct, as the autopilot took the car into the real left lane.
