I must have missed something in the text but doesn't the current production VW Golf (part of the same company as Audi) also feature traffic jam assist and lane assist? I think it uses RADAR instead of LIDAR but I don't know for sure. Could any explain what the new A8 is offering in addition to the Golf?
