Then when the **** hits the fan...you can react...and not have to try and figure out if your car is in gear, foot is on the brake, etc...you will be able to do it automatically.
Coasting in neutral up to a stop .......why would that be safe.....???

Coasting in neutral to a stop...I don't know. Why wouldn't it be safe? Don't tell me you're gonna accelerate if a squirel comes in front of you and you're trying to not hit it all while coming to a stop...

I know that I am taking the extreme safety viewpoint here.......
It's kinda like street racing...usuallty there is no problem...but does that make it safe??

However from a logical standpoint it is utterly off the topic, and has no relevance whatever.

I guess I would hope that no one else has to have the "improbable" happen to them before you see the logic in driving safely. Emotional...hell yes. If something almost killed your family you'd be emotional too.As for your LOGIC...

Would you not already be applying the brakes? If they did fail you would still have distance to slam it into a lower gear and engine break. Most people would panic and not know what to do any way. You sir are taking EXTREME safety viewpoints here, haha. It's good, but then it's bad. You have an E-brake for a reason...EMERGENCY brake...key word being EMERGENCY...use that to slow it down.

Gradually slow down using the brake pedal...I'm sure that your engine will be happier too if you don't engine brake.

Okay, I'm done whoring this thread. It's completely off topic now.

a) Shift at 3.5k
b) Avoid hills
c) Run red lights/stop signs (rolling stops are okay, too)
d) Drive once a week
e) Don't warm the engine
f) Do the Speed Limit

OK - to all those people that think coasting in neutral is a safe way to drive - do yourself a huge favour and spend some time at a race track with a driving instructor.
Once you realize how much more in control you are with your car in gear at all times - I doubt you will continue the practice.
However :
If you drive like a granny - it probably won't make a difference .

and 5 miles on a mountain road in neutral really does sound dangerous. I hope you AT LEAST keep it in gear going downhill...

If you need proof, get a wideband. If you believe in technology, read up on DFCO

Complete
Complete
Instant control over acceleration AND deceleration is safer, agreed?

Anyway thanks for telling me about the fuel cutoff, but I think drifting is still better, because you dont slow down as fast.

Of course you won't slow down as fast in neutral. But shifting to neutral and rolling will use gas while you're rolling.
If you're going 45 and you downshift to second, of course you'll slow down pretty fast. But leave it in 6th and you won't. You'll also use no gas.
That's all I can say, if you're still not convinced, then whatever

I would also say my engine runs strong it is a 8/05 build date 5spd. But my city driving is all city outer Chicago, no stop and go but stop lights every few blocks. I can get up to 45mph at parts but 30 is more the average. Doing this I get 12 to 12.5 mpg in the summer and 11.5 in the winter. I drive moderately aggressively maybe 2 to 4 red lines a day. Most the time the revs are below 6K.
On the highway I get between 18 to 22mpg. Dose this sound like your car.

With an automatic, freeway speed is modulated with the brake pedal. In my manual RX8, I am modulating freeway speed through the gas pedal, using a mixture of gas and engine braking to compensate for the vehicle ahead. If movement is getting back up ahead real quick (20 mph) and I'm going 70 mph, I am usually able to let gas off for a few seconds, shift into 3rd gear, then 2nd gear to slow down to 20 mph speeds without using the brake pedal.

So that's the deal—a thirsty engine in exchange for feel and handling—not power.

I think you two make a nice couple, all bickering and ****. You should hook up and get a room.....
Oh by the way, all city hard driving 8-14 mpg, mixed city and freeway 16-19 mpg even aggressive freeway driving 4th gear 80-90 mph passing, upshifts/downshifts etc., freeway 20-22 mph. w/cruise control. If you drive it hard you will burn the gas, but it is fun! I think its improved a little since I took it in for the recall and they flashed it. Over all with my driving habits I would say I get 18 mpg avereage.
And I agree you should never coast out of gear, thats why I coast with the clutch in and the tranny in reverse, just in case I have to stop quick or back up on the freeway.

[QUOTE=KimiFelipe]I'd never heard that injectors are cut/off or cut down during engine braking, so fair enough. However if you engine brake you lose speed a lot quicker than if you drift. In fact, I have driven for up to 5 miles or so in the mountains of Tennesee. >>
Computerized fuel systems will "lean down" mixture the moment you take your foot off the gas.

You just answered your own question. I have read many books about driving, and I do not think a single accomplished driver- street or track- would ever advocate deliberately surrendering control over the motor under ANY circumstance, and if you do want to get off the motor, this is done only through the clutch. There is an old expression racers use that Jackie Stewart wrote about: "When in doubt, both feet out," meaning stepping on the brake and the clutch at the same time in a situation where things get out of control.
Secondly, power itself is a control factor. Power can be used to quickly alter a car's
direction, and sticking it in neutral effectively robs a driver of this option.
I wouldn't even call it a matter of "opinion." Coasting is dangerous. Period.

[QUOTE=MP3Guy]
This is exactly what I do. Even when in gear I always depress both clutch and brake at the same time.
LOL another preacher. Everyone in my circle of friends who drives a manual coasts in neutral and thinks you guys on this thread are, to put it nicely, FOS.
I still dont know why its "dangerous" - you guys make it sound just as bad as driving with a tire or two having 5 psi of pressure in them, or driving with your eyes closed. _Exactly_ what is dangerous???
Especially in light of your Stewart quote - you always want to be able to slow down. In situations where I think I might have to suddenly speed up, I am in gear. It's not like I cruise out of gear every millisecond I'm not flooring the accelerator.
You guys are ***** about this ****. It's impossible to have a conversation about stuff on this board.

Some wacky ideas for saving gas with dubious results
Using neutral while coasting downhill:
This urban legend is a popular gas saver myth for foothill dwellers and weekend ski trippers. Not only is this ineffective at saving gas, but it is extremely dangerous. There's no reason to cut-off your acceleration control - coasting with your foot off the gas uses the same amount of fuel. And, letting your vehicle drift downhill can generate triple-digit speeds - one reason why coasting downhill in neutral is illegal in many areas. And if you're thinking of the next crazy step - turning off your engine to coast downhill - the cops should cut-up your license.
