At 2-3 car lengths, you're probably driving through disturbed air which is more likely to cause more drag than if you were say 10 car lengths behind the vehicle in front of you.
You, sir, are the idiot here. Drafting at a distance of 100 feet back @ 55mph fuel consumption decreases by 11%. 100 feet is roughly 5-6 full-size car lengths.
