Quoting Ed Parker
While it is true that we should adapt a martial art to suit us individually - and we learn to express ourselves freely and blend with the situations as they occur - a firm basis is still needed to learn from.

The Crossover / Cover Out
Described in Mr. Parker's Encyclopedia of Kenpo, a “Cover Out” aka “Crossover/Cover-Out” is described as: A single crossover and step through reverse to increase the distance between you and your opponent, thus enabling you to conclude your maneuver in a safe position of cover.
Although this simple foot maneuver is used in virtually every self defense technique in our system, very few practitioners actually understand it, or do it correctly. Harsh words yes, but after you've read this article, watch a few people crossover and cover out and see if you don't agree. By the way, I'm not picking on anyone in particular, but all you have to do is search YouTube.com with “technique line” and you'll come up with several examples of poorly executed crossover/cover-outs and very few people doing it correctly. Do your own search and you'll see what I mean.
So, first of all, why do we crossover and cover out after a technique? The three most important functions are to increase distance between ourselves and our opponent, surveying 360 degrees of our surroundings in the process, and to place our self in a favorable position in relation to our opponent. But what I see happening in schools, tournaments, exhibitions, and in many videos, is mostly one thing and one thing only – creating distance between them and their opponent . . . but very little of even that.
Creating Distance:
Creating distance is the easiest part of a crossover/cover-out. It would seem that regardless of how poorly executed, simply crossing over, stepping out and then stepping through, would put a fair amount of distance between you and your opponent. But even so, I often see this most basic element of Kenpo executed poorly or not at all.
What's happening is this; Most people don't look where they going when they execute a crossover/cover-out. That being understood, it's also understandable why they cover so little distance, as they're reluctant to sprint backward (any measurable distance) without looking where they're going. Therefore they take a small front crossover step away from their opponent, and then quickly step off to the side (to an area within their peripheral vision) and then . . . continue reading article
