Yes. Any car which requires a human to take over at any stage isn't autonomous. It assisted driving. A truly autonomous car won't have drivers control at all so using a hand-held mobile phone should be fine. On that note, it was interesting that thet statement didn't differentiate between a hand-held mobile phone and a hands-free phone, which ALL modern cars have the facility for. Hands-free use of a mobile phone is legal. Even m y crappy mid-range 6 year old car has bluetooth and voice control/steering wheel controls for my phone. A brand new AI car will surely have at least the same.
