please dont justify poor driving habits with ill informed information
Neutral coasting is dangerous, and in some cases, illegal.

whoever taught you to do it. was wrong.
P'wnd!!! i learn from this guy^^^^^

Guess it depends on time of year and mood. Warmer weather seems to richen up the mix and I get alot of crackle in my exhaust when it coasts in gear. I downshifted/left it in gear more then (probably because it sounds nice). Now that colder weather is uppon us (and my clucth is dying) I leave it out of gear more often.

It also seems toughter to rev match when up shifting in cold weather because the engine doesn't want to drop RPMs very quickly. So if I don't feel like waiting, I slow it with the clutch but the engine seems to bog for a second after fully clamped.

Engine braking is also illegal in some places.

how can it be illegal. when you let off the gas in a manual car, that's engine braking. so you're saying you're not allowed to take your foot off the gas? doesn't make sense bro.

no, it is illegal in alot of places actually. It has to be a significant change in speed, like an actual downshift specifically to engine brake. It's illegal because your brake lights don't illuminate so the driver behind you has no idea you are slowing down.

ex: 40 in 4th gear, downshift to 2nd, rev match and engine brake to slow down to 25. People do it. It's stupid, but people do it.

anyone who is arguing the fact the engine braking is illegal should look at the signs that say that use of engine retarders are illegal within city limits. thats what engine braking is.

its only illegal on large trucks, and only in certain areas.

where its nicknamed a "jake brake" ever heard that godawful loud noise when a big truck is slowing down?
yeah they arent supposed to use them in cities because of the noise
and that is not just engine braking, that is engine RETARDING....

those signs have nothing to do with small vehicle engine braking.
engine braking is NOT illegal in a car.

hmm i stand corrected. That's interesting that they have signs not specific to trucks, but it only applies to big rigs. weird.

Interesting indeed.

The signs clearly say "NO ENGINE BRAKING", but nothing about trucks or cars. On these roads that i've seen it on, they are more country then other types of roads. Small and narrow, 2 lane road.

well you obviously feel that your right.
i understand that, so im not going to sit here explaining it to you.

what i would suggest, is you just do a little googling.

5 minutes of looking about "engine braking" or "engine braking illegal"
and you will soon find out the truth.

heres a bit to get you started

http://en.wikipedia.org/wiki/Engine_braking

Legal implications
Compression braking, a form of engine braking, produces extreme amounts of noise pollution if there is no muffler on the intake manifold of the engine. Use of an exhaust brake produces similar effects, due to release of compressed gasses, but the mechanism is distinct from regular car engine braking. Anecdotally, it sounds similar to a jackhammer, however the loudness is between 10-20 times the perceived loudness of a jackhammer. Numerous cities, municipalities, states, and provinces have banned the use of unmuffled compression brakes.

This is often a source of dissatisfaction to professional truck drivers, some of whom believe that municipalities are taking advantage of them due to their transient nature, and thus disregard the law, believing that they will be gone before a complaint can be lodged.

and no offence. but its ****** scary how many people brag how well they can drive a stick, and dont even understand
what engine braking is.

Didnt you do drivers ed?
or even read the drivers manual when you took your test?

Not that I feel that I'm right, just stating what the sign near me says. Don't forget, it might not be federal law, but municipalities can have their own laws as well. It could very well be some municipal code. But then again, who knows, I don't!

And about driver's ed, times have changed ALOT since your day.

These days in drivers ed, you take a few tests and boom, you have a permit.

you still have to read the book.
and its in the book to use engine braking in conjunction with your brakes to slow your vehicle.

if a municipality made regular downshifting illegal, they would be laughed at.

I actually coast in neutral to a stop, but I do not use the clutch to get to neutral. I will wait until I come down to about 1300RPM and then it glides right into neutral from any gear. I have done that since day one. I've done that on any manual I have every had. Is that bad?

Some argue that is cause extra wear on the syncros, but I don't know that either. I just use the clutch and go to neutral.

what you are doing is called "neutral coasting"
and yes its bad. its unsafe, and illegal in places..
I strongly suggest you learn to decellerate properly with your car in gear.

There is no way you can tell me that downshifting does NOT use more fuel than coasting. If you can't figure out why, then I don't think you should be part of this debate. I don't really agree with your other "cons" either, but those are negligible, so I wont argue them.
as a matter a fact it does save gas
