Drafting as the geese do. Diagonally. Any pro tips?

So I am not an aero expert, much as I wish I were. Anybody out there got any advice on drafting cars that are in the next lane over? Specifically on ideal positioning- If you have professional aero advice, please share your thoughts. In my personal experience in urban heavy traffic there are times when it may be both possible and safe to do this. Depending on positioning, it could be just as safe as not doing it at all. Under dense traffic conditions anyway.

I should probably go watch some nascar as research. Or maybe ecomodder has got something. Birds and cylists seem to do well with diagonal drafting. It seems a lot safety-er (and legaller) than drafting guys in front of you. For the guys itching to post about how dangerous and stupid this post is.. Even in normal driving sometimes just by chance my car is in (what I think is) a good position to get a diagonal draft benefit.

When I have played around with drafting on a bicycle (with a friend, not in a race), we found that the best spot was with the front edge of the front tire about even with the lead bicycle's rear axle. To get that overlap, you have to go "diagonally" somewhat, of course. But you really want the two tires as close to touching as possible, to get more "behind" than "diagonal".

When geese fly, the flapping of their wings creates an invisible horizontal vortex. It to is this vortex that the following goose aligns its own wing for a boost.
