quote: Yes, constant speed = 0 acceleration. Constant Speed > 0 means you are either coasting downhill where friction is offsetting gravity, or you are using the engine. At constant speed, your hybrid batteries are not recharging UNLESS you are burning gas to do so. Even if you are using your batteries at constant speed, they will run out and you will only be using gas (and your little engine will work extra hard to maintain say 65-75 mph). |

What, no reply to me, NoSUV? Funny how often that happens.
Or are you still aghast that you bought a Japanese car whose principle global effect will be to reduce, infinitesimely, America's hegemony? Are you a Cheney-lover? Look out! He's got a gun! [:)] |

NoSUV, if you read my earliest posts again you will see that I worked on climate change mitigation projects for two years. But I don't claim to be Mr. Greenjeans, like you.
The 15% to which I refer actually covers ALL transportation fuels, including those used by railroads, semis, ocean liners, automobiles, airplanes, helicopters, and Wonder Woman's invisible jet, too. Of the 15%, how much of that is from private autos? Not much, actually. Only automobiles are subject in the U.S. to emissions standards while the other fuel users can spew black clouds of diesel into the air. Your hybrid is a feel-good smug-machine in terms of its environmental impact. Want a good reason to own one? Reducing gasoline consumption reduces the need for the U.S. to maintain control of the Persian Gulf states. Driving a hybrid is like spitting in ExxonMobil's eye and managing to hit Dick Cheney at the same time! |

NoSUV, a hybrid recharges it's batteries when either a.) The engine turns the generator, which burns gas, b.) coasting shifts kinetic energy to the generator, c.) braking shifts kinetic energy to the generator.
When driving on the highway at a constant speed, you lose the benefits of options b and c. So to maximize battery generation to use more battery power (which would use less gas), you want to be coasting/braking a lot. You cannot do this on free flowing traffic at high speeds, otherwise you would cause an accident around here. But by staying on the regular lanes, you can coast and brake much more frequently. We all now though that you hate the regular lanes and thing you should be priveledged to drive SOV on the HOV. I think this is just a very elaborate plot of yours to clog the HOV lanes so that there is stop and go traffic on it, thus allowing you to get more efficient use out of your batteries. This seems unfortunately extremely selfish. |

scottt - better in bumper to bumper? Which scientific papers are you quoting? Do you have any empirical data?
Are you assuming that the vehicle does not accelerate in bumper to bumper? Or that it accelerates less than when at a near constant higher speed? Or are you just making things up because you so very much want to believe it? Buy a hybrid, try it out, then report back your actual findings. Right now, I'd have to say that you are wrong, wrong, wrong. |

Hooch,
I'm not in the vast majority of which you write. I bash hybrids at every opportunity. I bet you $5 that your neighbor rarely, if ever, picks up riders. Hybrid ownership isn't about anything but riding solo on HOV. Got it? Respectfully submitted. |

KnowSyouV - wasn't referring to violators or cheaters, I see very few of those without CF/CX tags, and it's usually around the cutoff time somewhere along my 20+ mile slug ride. I was referring to the SOV greenpeace squad cars.
And for the record, the vast majority of the posters here (myself included) don't hate/bash hybrids. They are better for the environment no doubt. But, to own one and drive alone preaching that you're saving the planet because you care is a bit hypocritical don't you think? My neighbor owns two, alternates driving them from Rt 234 to D.C. every day, and picks up riders. She also recycles and has an electric lawn mower. I'd say she's one hybrid owner that cares, and that I don't see as a hypocrite. Hooch |
