Unlike vehicles from Google Waymo, Uber and others, the car didn’t have any obvious signs of a Lidar array, the chunky imaging technology most autonomous vehicles use to gauge the state of the road ahead. Instead, it had just a small bar mounted on the dashboard, which blinked red when it was at a stop light and green once the cost was clear.

Even more intriguingly, the car appeared to be genuinely autonomous: there was no-one sitting in the driver’s seat. Typically, a human overseer is required in the testing phase to make sure that the car doesn’t go wild and run over a marching band, but somehow this car had managed to find a loophole.
