No they don't, it's why they still build multi-million dollar windtunnels.

No it isn't, rolling down a hill is a real world, hard fact, can't deny it, test of whether the thing works or not.
Too bad you didn't check with us before you spent God knows what on your computer simulations. Fact is, I'm here at ecomodder because I was going to invent magnetic stick-on golfball dimples to put all over a car. The folks here helped me to see the err of my ways when I stumbled in here while doing research.
A computer simulation is a fantasy world collection of numbers that may or may not account for the insane amounts of variables that exist in something as simple as air moving around a car as it goes down the road. If it were a simple thing, a computer using 32 64bit, 3.2Ghz processors wouldn't need 8 days to figure it out.

It's pretty darn close, it's a pretty basic fact about aerodynamics, you should know this. FWIW this 50% thing is for highway speeds, in town, it's much less. (Meaning, if you aren't hitting the highway a lot, your gaspods are even less effective)
Here's proof, see that "Power to Wheels" 17-21% and "Wind Resistance" is 8-10%, there you go, cut wind resistance in half, improve your fuel efficiency by a quarter. Or 50% or your Aero Gain is Fuel Efficiency gain.

Bad data is bad data whether it is 2 numbers or 30,000......surely this does not have to be explained to you.

Of this I cannot disagree, however, you are making a claim or inferring that drag reduction by gaspods are the reason for the savings. This I contend is not true.

Show me where it says this. One article in the mainstream press or on AAAs website or anywhere else. Should be easy enough to find since countless lives have been lost by people coasting down a hill for a mile, there are certainly warnings a plenty about it.
Think about it, if you coast down the same hill 10 times, alternating pods on/pods off going the same speed of 45-50mph at the starting point, shifting into neutral, then timing how long it takes for you to reach an end point and noting what speed you're going, you'll know pretty quick if there is a 10% reduction in your aerodynamic drag. If you find the right hill, you'll be going the roughly same speed the whole time. Certainly there are plenty of long downhill runs in the LA area for you to find which have minimal traffic, and late at night, no traffic whatsoever.
You don't even have to put the results on your website or anything, just tell us here....it'll be our secret.
