This happens if your passengers are on the heavy side too!

Neutral is like sitting idle at a stop light.
You use a little bit of gas to keep the engine going.

If you stay in gear down a hill, you use NO gas.
The momentum/gravity/potential energy keeps the engine going.
What keeps the pistons moving in the air pressure that gets pumped into it by the cars computer (ECU).
This is proven by the oxygen sensor (O2 sensor) being at 100% when going down a hill or even coasting to a stop light.

In addition, by staying in gear going down a hill the resistance of the engine/transmission helps maintain your speed saving your brakes (this is called engine braking). It is recommended down a long or steep hill so you do not wear out your brakes, but I would not recommend doing a lot of engine braking purposely/in daily driving, such as down shifting; it’s cheaper to replace the brake pads than the engine/transmission.

(Of course, it depends on conditions more than watching console bars. Accelerating from a stop to a speed that will be maintained is different from accelerating from a stop for only a block before another stop.)

The huge “working space” is certainly okay in sparse traffic — where it accomplishes little — but in dense traffic it’s annoying and it affects traffic patterns long after you’ve moved on. I’d call it passive-aggressive driving in some sense.

(It seems to me that the major benefit of a hybrid is regenerative braking, so if I have enough room to not have to push too hard and mechanically brake, it’s all good anyhow, yes?)

The high-pressure tires part actually scares me a bit. The manufacturer recommends tire pressure based on the car’s handling, among other things. I wonder what your low rolling resistance does in an emergency situation or in poor driving conditions?

To be honest, some of the advice sounds like it might be more applicable for non-hybrids.

Using simple electrolysis- break water into hydrogen/oxygen and inject it into your air stream. It mixes with the gasoline and cause it to burn more completely – giving you better mileage, and cleaning the exhaust emissions dramatically.

Combine a simple electrolyzer and 3 oz. of Acetone per 10 gallons of gas and get 50% OR BETTER increase in your mileage- all while cleaning the environment as well.
