Yup, and I have virtually NO depth perception. That's why I run bright colors, and run pretty much the center of the lane on the back side of the track usually. It helps me keep from hitting stuff, even if it isn't the fastest line. It is also partly why I run truggy instead of buggy- bigger is easier to see, easier to tell what it is doing.
