China, of course, it’s China that got there first. But it’s not Geely or SAIC but Changan that holds the Guinness World Record. They took 56 of (what looks like) their CS55-based autonomous SUVs and made them go through a closed test road at 30km/h. They each had a driver on board and one of those drivers had to take over control, so the record now stands at 55 cars.
