"A so-called Traffic Jam Pilot system takes charge of driving in slow-moving traffic up to a speed of 31mph on motorways, where a physical barrier separates the two carriageways. The new system manages starting, accelerating, braking and steering functions.
But without a legal framework for its operation in many markets, Audi says it will adopt a step-by-step approach to the introduction of its new autonomous driving tech."
The Traffic Jam Pilot is a level 3 autonomous system. It's not legal to use as such in most places.
