He changes gears exactly when and as required and even displays excellent understanding of traffic flow and reacts well ahead of time to situations - for which of course, I take credit. Still I see no need to make any changes. Economy is not a biggie for him.I don't see it as an advanced technique, just a dangerous technique.It's not about getting it "right" because there is no way to get it right.When you are travelling in a car at 60, 80 or 100 km/h or whatever, without it being in gear, the fact is you are not in control, the laws of physics are.You can steer and you can brake but you need the full trifecta to have proper control.Anyone can do it, but I just wouldn't recommend it as a safe driving practice.

Old car with a carburettor – take your foot off the accelerator pedal with the car in gear and fuel is still drawn through into the engine. Fuel savings could be made by coasting out of gear.
The difference being the legalities, I guess.We have a charge here of "Not being in full & proper control of a motor vehicle" which I would contend would fit this scenario.

If I get the chance I shall ask our local police officer and report back.
For better fuel consumption, be careful where, when, how you use the Cruise Control.CC doesn't think ahead for hills so it doddles along happily until the car starts to loose speed on the uphill and then slams down a gear or two in a mad dash to maintain the set speed.
Having said all that, I am often happy to sacrifice any fuel saving for the benefits in staying under the speed limit and being able to devote my concentration to other things (like the idiots around me in the traffic and the road conditions).

Something to do with it being a manual perhaps?
Interesting thread,some interesting comments,I only have one thing to say about coasting,lets all take our driving test again and see if any of us pass if at any point in the test any of us coast in nuetral,I think not.

Me, on the other hand, most people would say not. However, in this point I'm happy to push the line that because most people cannot safely determine when and if "coasting" is useful, sensible or even safe then like lots of road (and other rules), we need to assume most of us are stupid.I like to think I'm not and can tell the difference well enough to see that coasting (in any form, in or out of gear) is only unsafe for those that are not able to control their vehicles in all conditions. Sadly, that is most of us.

I noticed coasting down a hill recently the car may have disengaged the gearbox as engine speed dropped to an idle during the descent. If this is in fact what happened then possibly manual hypermiling techniques may not be as necessary.
yes I agree it is possibly safer left in gear, but in Hypermiling, engine braking can sometimes be the enemy.
This thread IMHO is the most pointless, waste of time thread on the whole forum, and it should be locked then deleted, anyone making mention of hypermiling or being a tight ar5e (because lets face it that's what it boils down to) should be banned for life.hypermiling, get in car, sit down, wind window down, pull keys out, throw them out of window, walk, there is your fuel savings.You bought it to use, you bought it because it ALREADY is fuel efficient compared to that VS commodore, enjoy it, want more fuel efficiency? buy a push bike.
I don't know the price of fuel in OZ, you obviously have money to burn, buy a nice v8 gas guzzler, I would if I could afford it.
