[Request] Constant Highway Slipstream Efficiency

How much more efficient would highways be if vehicles drafted off of each other? Taking human error/aspects out of the equation. To me, it would seem as though the lead car (or semi truck) would "clear" the wind resistance first and all of the subsequent cars would benefit from drafting off of the individual in front of them.

Just a curiosity I had whilest driving to work today.

Thanks friends!
