Co-Assist Is a Level Two System, So, What's the Difference?

Christoph, why China for starters and when are you expecting this to be on the road elsewhere? I guess China, because there is first a very, very strong appetite from the consumer that you had technology content to the vehicle. And as I mentioned before, the idea from the very beginning was to find the right combination between functionality and cost. If you can make it happen in China, at that price level, chances are it's very, very competitive. It can be transported in other countries as well. Some of these solutions are easier to implement in the current regulatory environment in China than it would be in Europe or in the US.
