Note to dialup users: Video is a 20MB mpg file and will probably take 5-10 minutes to download. Recommend download to hard drive.
It took a little work to figure out how to pulse and glide behind my home in the alley and down the street to the first stoplight 0.4 miles away, but here is a video and still pictures illustrating how it was done.
Typically I do this at 6am when traffic is very light. Normal driving would get a result of 50 mpg in my Insight - P&G as illustrated yields 100-200mpg (139.5mpg in this instance). While I hand anchored the camera against the sun visor, it will still be a bit shaky - sorry.

A video description:
Already off the ramp in behind my house in the alley with a half-second pulse and glide to exit the garage and climb three feet (one meter up the alley)
(Begin Video) Start the car
Get to 25mph in 20 yards. (Fast - I usually cut off at 20mph. Yes, I brake for children and jackrabbits)
Cut ignition (dash goes dark) No more gas on the rest of video!
Glide 100 yards or so down the alley, turn ignition back on. Ignition has to be off 2-3 seconds or engine will "diesel" back on and defeat the gas savings of pulse and glide.
Sharp left turn (wish the Ford F350 was at the end of the alley this time for a Doom II monster effect :D )
Go 20 yards to the end of alley into resdential street.
Sharp right turn to residential road. Don't worry - the silver PT Cruiser is safe!
15 yards on residential road
Sharp right turn to get on major road. I do look for oncoming traffic.
Glide 0.2 miles downhill to traffic light. (End Video - see pictures below) Got 139.5mpg instead of the typical 50mpg at this point. I've gotten 100 to 200mpg.Pictures of the Rest of the Glide After the Video
MPG reading in alley: 20mpg

Past the alley on the major road at 0.2 miles - 66mpg

Crested a hill starting to accelerate to the stoplight ahead - 92mpg

Almost there

Finally at the stoplight 0.4 miles from home - 139.5mpg.
What if the light turns green? It's a bonus - turn the engine on, get up to 30-35mph, coast 0.5+ miles to the next stoplight.
Maybe this makes an excellent case for EV mode. :D
