What is the real difference between the auto and standard pinions?

I know the difference in ratios, and all that.

And like I said, I'm not going to be ripping through gears just top stop every 8th of a mile. I drive like a grandma, even when I drove a built V8 car. People always complain about how I drive. Even in my Cutlass and my old GTU, I rarely hit the speed limit by the time I got to the next light.

I despise highway driving here because I have to pass the most advanced weigh station in the US or something and it never fails to get bowled off the road by retarded truck drivers.

Honestly, I enjoy taking 25 and going through town, even if it means I have to leave 15 minutes earlier.

How much is the actual difference between rpm vs mph?
