If you are worried about staying in the center of the lane, on my ACE I found that if I look at the defrost vents at the windshield, the right edge of the second vent on the drivers side will be just inside the white line of the road then I am centered in my lane. I also have a toad and keep my rear view camera on, also helps to look at the toad to see its in the center of the lane. Not sure if that helps any or not.
