And my trials are done. I achieved 27mpg with a almost 50/50 split of city/highway, but decided i just couldn't drive like that all the time.
Personally, i'm not worried about gas that much at this point, and would not mind seeing $6/gal if they would take those extra $1.50-$2.00 in taxes to rebuild the roads to a better spec and bump up the speed limits to say 100+ in rural settings, and 80 in cities.
My 22-23mpg in town comes from driving smart, things like not accelerating to a red light when i can coast just fine, pulling away from a green slower, keeping revs around 2k on acceleration....I use the full potential of the V8 sparingly, but when i do use it; it's there in all it's glory.

It's not about saving gas to save money, it's about not squandering it when i don't have to.
Speaking of a more fuel efficient car, i test drove a Camry hybrid last week, and it was GUTLESS, it would take a lot of getting used to, personally.
Another thing, i also have an ES that gets 16mpg regardless of whether i drive it hard, or easy like i do the GS. I would have gotten rid of it long ago if i didn't have so much fun revving it up to get going.

I "hyper mile" and coast down hills in neutral. Oh, but I drive a stick, where when you shift it back into third there is no delay like an automatic. I must say I am impressed with the RX400h's coasting ability.
+ 1 on transmission wear and tear on an auto.
Also worth noting, in a manual transmission holding the clutch in while the vehicle isn't moving rather than putting the vehicle in neutral will cause more wear to the clutch.

you actually use more fuel coasting in Neutral. here's why. when in N, your RPM goes down to idle. to prevent from stalling, the engine must give fuel to maintain at idling speed. now, when you're coasting in D (even if it is in 4th gear) the RPM is higher than the idling speed. and because you're not pressing the accelerator, the fuel delivery is off.

I always figured it went differently, when i had my Yukon the mileage display would always go to 99mpg in neutral when coasting (I also did a mpg test on that, and came out to 19mpg in town, and 23 mpg combined at the point where i maxed out)

Relax, i never did the neutral thing that often.

Coasting down long steep hlls in neutral is DANGEROUS.
Although there were some good hills in the VA mountains west of D.C. where I lived, here is the THE hill on U.S 40 in western PA (Uniontown) where I learned, as a teen-ager, how to downshift for engine braking......three and one half solid miles at a 12-15% grade. Coasting in neutral here would mean burned-out brakes and maybe suicide.
