2) Ever watch the Tour deFrance and notice men with tights, elongated helmets, bikes with airfoil shaped frame tubes and so on? They are counting grams of air drag force, and all the aero shapes help to make them more efficient. Could you imagine riding a *normal* road bike at 30 mph for one hour without these benefits?

3) How about anyone with a Velomobile. Imagine being able to *cruise* at 30 mph instead of 20 mph. The airfoil on the bike allows this to happen.
Sure, but those have motive power sources in the fractional HP range.

That 3+ hp on a Metro from 45 to 55 represents what- less than 7% of available power.

On something with a bigger engine to car ratio (most anything) the percentage is even less.
