Replying to: quasar4 (Nov 20, 2005 9:35 am) This happens because we are so "virtuous" in what we say, and "law-happy" in proving it. On the other hand the majority of people ignore the law, feeling they have special circumstances, or driving expertise to drive faster. The problem is that the laws should reflect what the majority is doing; not necessarily what they say. People who do drive the speed limit in most places, are increasing the dangers of the road. you: i was minding my own business --just driving along trying to beat red lights-- when some idiot in front of me decides to slow down early for a yellow light instead of trying to run it like everybody else. Can you blame me for plowing into him??" me: you better not go to Boston/Mass then. never stop for a yellow light or you'll get rear-ended. You're always better off taking the chance of getting a ticket.

Replying to: kernick (Nov 20, 2005 4:26 pm)  You mistakenly equate "slowing down early" to "slamming on the brakes late." Nobody is advocating stopping early for a yellow light --merely slowing down early so that if you see a yellow light ahead, and you can't safely avoid the red, let off the gas and coast up to the intersection. Better yet, if you see the light change from a block or so away, slow down and try to time the light so that you're still carrying some momentum when it does change back to green. Improvements in real-world MPG certainly do not result from slamming on the brakes*. I'm sure you would agree that if you have to mash the brakes into the floorboard to avoid entering the intersection on a yellow, then you're just as big of a tool as the guy who sees the yellow with plenty of time to safely slow down and stop, but decides to mash the accelerator and gamble with his life and the lives of others that he can beat the red. *Long-term '04 Prius gas mileage (Jan. '04 to present) is 53.92 mpg and rising.

Replying to: quasar4 (Nov 21, 2005 8:46 pm) Coasting up to yellow lights from a distance is okay. Applying the brakes upon yellow, 1 sec from the intersection is dangerous. I suggest accelerating to make it thru the intersection under yellow (running it), and eliminate the chance of getting rear-ended, by the occasional person who is aggressive and is going to follow you thru. |

Depending on the kind of driving you do, and what you're comparing the Prius to, the economics of the Prius don't make much sense. Especially when you factor in the battery replacement cost. A large majority of my driving is on the highway at 110km/h or 68mph, and overall it seems that getting the EPA hwy numbers for these vehicles at these speeds is pretty reasonable. So at CDN90cents/Liter I would save about CDN$4000 over 150,000 miles in fuel driving the Prius but THEN I would have to deduct about CDN$2000 from that for the battery replacement. I'm assuming the Matrix would not require CDN$2000 in drivetrain repairs at 150,000 miles, which is a pretty reasonable assumption as it's the Corolla drivetrain. The MSRP difference between these two is about CDN$10,000. As far as GHG emissions go, these kind of dollar figures could take you very far towards getting your house on wind and solar either directly or indirectly. (i.e. some utilities allow you to specifically pay for "green" energy)

Replying to: rdeschene (Dec 21, 2005 9:19 am) There is a whole forum on battery issues ("The Great Battery Debate"), that discusses this unknown. However, Toyota believes that the battery will last as long as the vehicle itself. They keep the battery between 30 and 80 percent of charge capacity to extend the life. However, in general you are correct. If you are driving a small car already, you may be achieving about 75% of the MPG of the Prius. If you do all your driving in the city it is a more dramatic difference (provided you are not doing short trips - the Prius delivers much worse MPG if the engine doesn't heat up). It is all a matter of your driving needs and expenses of the ICE car you currently drive.

Replying to: stevedebi (Dec 21, 2005 1:01 pm) Personally, I do like the "large hatchback" design and wish they had such a version with the Camry 2.4L engine for those of us for whom that makes more sense. They could label it a Camry if they wanted to, and it would be interesting to see what the total weight would be with this substitution -- it might actually be lighter than the Camry sedan and give slightly better highway mileage (EPA 34mpg).
