Default Is average RPM driving not good?

Question??? Sine I've gotten a speeding ticket a few years ago (155 in a 55 and a night in jail) on my motorcycle im very cautious about going fast. So I'll say MOST of my driving will be done no faster than 70mph. With these cars being so high strung is it in any way bad for the tuning of this motor to be consistantly driven at these low rpms everyday?

70 mph it wont be low rpm's. Will be around 4k. But to answer your question. Absolutely not.

I keep my RPM around 3k for city driving, but no I don't think it's bad because I cruise at 40mph in 6th, 2.5k RPM, all the time.

40 mph in 6th, yes even Honda recommends driving in the highest gear as possible for fuel economy.

Actually I heard its better to keep the motor at at least 3, anything under and your lugging the motor. Believe it or not the engine has to work alot harder to accelerate under 3k rpm. Quoted directly from the manual

Recommended Shift points

"Drive in the highest gear that lets the engine run and accelerate smoothly. This will give you the best fuel economy and emissions control.

1-2 15mph
2-3 25mph
3-4 40mph
4-5 47 mph
5-6 52 mph"

If your doing anything under than 52mph in 6th gear your making the engine work harder than it should and actually decreasing fuel economy.

we had somebody actually test this not long ago and confirm it--it seems like our cars like to be revved until they build up a bit of torque or they aren't as efficient, so the typical slower uses less gas only applies to a point. (and that point is the recommended shift points)

As long as the motor is at operating temp I like to shift at 8k!

Seriously, I've been driving manual transmissions all my life. What the manufacturer recommends in the manual is just that, a recommendation and usually for economy. After years of driving a stick you should be able to tell where to shift the car just by sound and how the power feels. For just tooling around I don't like the revs to drop below 3500rpm.
