Tesla says that all the cars it produces will now be capable of driving completely autonomously. A video released on Thursday shows a demo of a car driving itself – with a human in the seat "only there for legal reasons". The car appear to pull out of a garage before a man gets in. The vehicle then sets off, the steering wheel moving while the driver's hands remain hovering just above it. The video ends with the car pulling off a manoeuvre tricky to many human drivers: parallel parking. The video – which is admittedly rather stylised – follows Tesla's announcement on Wednesday that all cars produced in its factories from now will be equipped with "the hardware needed for full self-driving capability at a safety level substantially greater than that of a human driver".
