This is the lane keep assist feature. It's amazing. Unfortunately, I don't think we get this stateside. This video is a full reveiw. You can forward to the 1:10 mark to see the feature in action. Peep that the reviewer is going down the road with his hands off the wheel...simply amazing.

yeah its pretty cool, except its kinda dangerous at the same time. It sways the car a bit much, back and forth between the lanes if you completely let go.

 

that is true but it's a great first try. I figure with some more work and refinement, it will be useful.

 

wow thats awesome :P
