AP911:

The new A8 is the first to offer level 3 autonomous drive. Hopefully in a year or two they can increase the speed limit of the level 3 from 60km/h to proper highway speeds. But they are the leaders of the pack. 

I know that Audi claims that but from what I do see, my Volvo and the Tesla is going further. So not sure about. 

The limit to 60 km/h is because of regulations. All other vendors are doing the same until 30km/h. Above that - only the A8, the new Volvos and the Tesla can drive 15sec without touching the wheel. I usually just have lightly my hand on it and let car do the steering job. Nevertheless, I always are aware what is going on.
