I've never heard of that before (not a motorcycle rider), but watched a couple youtube videos on that now - yeah indeed, road cyclist do this all the time. This is really enlightening. Even watching Remco's Lombardy crash again, that's at least partially exactly what happened there.
Weird how many cyclists put so much pain and suffering into training and yet fail to learn the simplest crafts of their job.
Not only for pro's, it always amazes me how many cyclists, pro and amateur, do not know this very basic rule. You go where you look! So look where you want to go!
So in that regard, doing moto gp, cx, mountainbike, ... anything will help him ;-)
CX probably the least dangerous option.
