Thanks l3ement.

Rebooting is a way to force autostop while still rolling down the road.

The technique envolves being in a favorable place (flat or downhill) where you take the car out of gear and manually switch the ignition key back one click to shut down the engine, then immediately switching back to run but not restarting.
The electronics in the car will reboot.

This will allow your HCH to travel with zero fuel consumption.
It is a way to dramatically increase your average MPG.

Things to consider about doing this:
1.Your electric steering will be sluggish for a few seconds after rebooting.
After you hear a relay "click" and the airbag light goes off steering is normal.
2.Depending on the situation, driving without your engine on might not be safe.
3. If you have a CVT don't restart your engine going over 40MPH.
Even if your shift is in N, if you're going over 45 the drive takes a hard jolt, which can't be good for the system.
4. You won't get any regeneration while your engine is off.
5. Repeated use of the brake pedal can deplete the vacume assist.
If you are out of vacume then the brake pedal will be substantially more difficult to press.
6. Pedestrians may not hear you coming and walk right in front of you.
This almost happened with the idiot skate board rider in my neighborhood.
Poor guy was so suprised to see me that he almost fell to the ground.

Personally, when I first leave my house at 3:00PM I'm battling a 2 mile gradual up hill. MPG is not good especially on a cold engine and I hate it.
After 10 miles going basically uphill the engine finally begins to warm up.

I drive back through that route at 3:00AM and the roads are virtually abandon. If I'm paticularly behind in MPG there's about 3 places ranging from 1-2 miles where I can safely just roll going 40-25MPH.

Efficient drivers do it better.
