37+ mpg in a 2014 Honda Odyssey

1) What’s the percentage change in total braking distance from solo for the fully-loaded van?

Consequently, what is the minimum highway spacing distance requirement in any of these?

You know none of this, do you? Consider your “skill” (ha!) somehow above reproach. Without this beginning, you don’t know “safe”.

Your premise of time-wasted is a giant self-deceit.

As was said long ago, “You know neither the hour nor the day”. (Understand this and the rest isn’t necessary).

And the same for all others who find auto travel a burden. To, get it over with as fast as possible. Who thereby make a mockery of shared responsibility with every demonstration.

You want it in Eco Modder terms? How many highway braking or deceleration events after entering, but before exiting?

“Travel speed” is the province of fools. Traffic volume dictates travel speed as surely as the sun rises in the East. The upper limit is constantly in modification according to it and other factors, equally-weighty. (Which should have been appreciation of tire slip angle and lateral acceleration; no van is capable of much while solo; but loaded?)

I’m all in favor of the use of cruise control. In which, how often did you cancel cruise control to get someone passing around you more quickly; that they could return to the travel lane 200’ or more ahead and thereby all avoid pack formation near your vehicle?

Was there ever a time you were surrounded by vehicles fore & art? To port & starboard?

Count yourself a terrible driver if this was avoidable in any sense whatsoever. The definition not only fits, it is statistically-valid.

The premise to travel is to arrive in the same shape as when departing. How that is achieved is the task. Driving for FE is a subset. It is finesse.

That finesses is the cruise control set speed most appropriate to elimination of braking events. and minimization of CC cancellation all while maintaining never less than 200’ of spacing (goal of 600’).

You, and others like you, have a long ways to go in becoming able to drive economically, as you haven’t first made a study of, much less mastered, “safe”.

I see your type daily. Never an understanding that what is overtaking in the mirrors counts for more than what is out ahead. A bright 12-year old can be taught the latter. But we’ve imported millions incapable of abstract reasoning, thus incapable of deducing the former. (Which is before visuo-spatial skill).

No one cares about your self-regard (self deceit) nor about the absence of negatives (citations, accidents, etc; same pride exists with those who’ve avoided arrest and prison sentence), but only about how well you are managing (making decisions about) what is happening around you, and how well that is being done.

Others far better than you are constantly having to take your selfishness into consideration of their own actions. But you believe (act the Fool) that your faster travel rate merits you (guffaw) special consideration.

Got news for you: The passing lane confers no ROW. None, except in the short moment of a pass. Never in overtaking. Also, one cannot block access to the passing lane (this list continues long and pitifully).

The day those better drivers don’t extend that allowance for your bad manners may be your last. Or, far worse, for one of those passengers. Perhaps that death is preferable to quadriplegia, as no long years of suffering ensue. Works better with Civil juries, that much is true.

Accidents aren’t accidental. Nor do they have single cause. So start by shoring up the timbers.

I’m appalled that EM is apparently, “engaging in the same unconscious bad behaviors, but for a lower out-of-pocket expense”. (The owner/moderator will be proud). But maybe not surprised at the fanboys around here of the electric car debacle unfolding at present whereby tech (Big Brother) is the only one accountable.

“Be a man” has become an exhortation without an echo.

.

Surely you're speaking to the audience in general, and not to me in specific, considering you've never seen my driving behavior. I'm more aware and concerned for the safe and efficient travel of other drivers than 99% of the general population, granting that there are surely some that are better than me.

Many good points here though, and I agree that people generally don't sufficiently consider how their driving behavior impacts the safety and efficiency of everyone else.

The vast majority of my highway travels involve zero use of the brakes until exiting, and I use CC as often as I can; choosing a speed which agrees with the average speed of the lane in which I wish to travel and minimizing the amount of passing or being passed.

When I say that I travel faster with other people, I'm talking about choosing the middle lane of travel rather than the slower tractor/trailer speed of the rightmost lane. Middle lane flow is often 5 MPH faster than the speed limit, and rightmost lane 5 MPH below.

The allusion to the lack of skill of immigrants is unnecessary and tactless. Sure, central and south american driving culture is more chaotic and those influences are seen in the US, but we can discuss good vs bad driving behavior without need for calling out groups (or individuals that you don't know).

None of your profound driving observations have gone unnoticed or unconsidered by me, but your ability to affect change in others diminishes when you create an oppositional tone rather than an invitation to deeper understanding.

Daox, have you asked the owners if the readout is accurate? I own a 2005 Odyssey that I have a hard time getting to mid-20s. That is a much newer van but still. I guess that number is the peak, not average which is not "fair" to compare.

Regarding cylinder deactivation, I... deactivated mine. I didn't like how it transitioned and apparently it's not very good for the car.... The system contributes to premature failure of expensive, electronic engine mounts and causes carbon buildup. I believe Honda actually lost a case on this (different model). Deactivating the ECO mode is a popular mod on my gen Odyssey.

In my humble opinion, some "eco" mods are just not "worth" it.

I'm not Daox, but my dad works at a Honda dealership and he said that the generation of Odyssey's from 2005-2010 got lower gas mileage than the previous generation. It wasn't until 2011 where the Odyssey's fuel economy became "legendary", per se. Until 2011 Toyota minivans were probably the most fuel efficient choice for a minivan.

I got 32mpg in my parents 2005 odyssey back when they had it at 70mph here in sunny CA, and that was with running the AC on and having every single seat in it occupied + cargo.

I dunno...my Mom's '04 Sienna could never really see much above low 20s, but caveat! It was all wheel drive, was an all-around basket case, and although I hadn't stumbled upon hypermiling per se, I did have my Dad's proto-hypermiling instruction, a calm driving style that suited something like a Sienna and which I generally practiced when I borrowed it.

Ours is 2WD, but I can't imagine that alone being worth that many MPGs.

He also gets better MPG in Mazdas than Hondas, despite Hondas being more fuel efficient.

[Daox]

Nope, I haven't asked them. They aren't too concerned with MPG.

As for cylinder deactivation, it certainly seems to be working well on their vehicle. It has nearly 100k miles on it and as far as I know they haven't had any issues with the vehicle.

[mpg_numbers_guy]

But any car properly maintained should last to at least 300K miles, what's 100K?

Who knows. Lots of variables there. That thing was such a junker from day one (I mean this quite literally), that it was deleted from the driveway with 19,000 miles on the clock. Was it running correctly? Did it ever even fully break in? The AWD setup eliminated the room for a spare, so it ran run-flats, but they were toast by 7500 miles - low tread and delaminating. She ran regular tires and bought a wheel and tire to carry in the back. Who knows how that affected it? And to be honest, my best trip was IIRC around 23mpg, but that was traveling from the South Bay Area, up and down the coastal range, and down the PCH to Big Sur, so not the best of terrain. Maybe I'm being a bit unfair to it, but then it gave nobody in the household reason to think very highly of it.

All I know is that my Chrysler can beat the pants off of it
