I would guess that is to keep someone from getting panicked and putting the car into the wrong gear. Hitting 3rd when you are shooting for 5th can be a little shocking

In an emergency situation when you need to accelerate, it's quicker to just let out the clutch and put your foot in it. Putting the car in gear takes an extra fraction of a second, which can make a difference, also it's another thought process you have to do while panicking, another thing that can go wrong. OTOH, most hypermilers aren't going to be in a gear where they can accelerate quickly anyway (5th @ 30) so you're still going to have to shift gears.

You can say that again! A couple years ago me and a friend of mine took a roadtrip with my truck, a 5spd, and he'd never driven a stick before. 15 minutes in a parking lot to get the basics down and we were on the freeway. 14 hours in, he's driving while I'm sleeping. He'd shifted down to 4th to make it up an Appalachian foothill and was trying to shift up after cresting the hill. 3rd gear @ 70mph downhill and he dumps the clutch! Engine redlines and tires squeel and I'm awake now! I've never broken tire loose at that speed with turning or the brakes! Just thought you guys might enjoy the memory jazzie jogged. On a side note, he got better at the whole manual thing the next car he bought was a Jetta TDI 5 or 6 spd, I'm not sure which.

Im glad that nothing more than a rude awakening happened, because at those speeds really nasty things happen, I work with an accident reconstructionist and sudden loss of traction at 70 is just ugly. One more reason to make sure everyone here is keeping their head in the game while they are eaking everything they can out of the gallon. Its like the drafting issue, make sure you're not endangering someones life in the hope to get a little extra mpg.

For the uninitiated, can someone explain what "bump start" is and how to do it?

Whenever I do a EOC, I always make sure I'm in neutral when the engine goes off and when it goes back on. Otherwise my car makes a loud metal-crashy noise that doesn't sound very promising.

Thanks! Seems like it can only be done with a MT, not AT, though. Am I reading that right?

Yes, bump starts are for MT only.

With many ATs, you can leave the vehicle in "D", make sure it's in TC lockup and turn the key off to cut fuel delivery and engine brake. Then, you can turn the key back to the On position without using the starter.

Modern engine will cut fuel on decel anyway (DFCO), but if you need that in-between of compression braking without downshifting into a more aggressive gear, it's something to consider.

Since you lose ABS, Airbags, and most importantly, the Radio, a fuel-injector cut switch might be the best option for this.
