If you have an Insight, sure :P

When I had my FR-S with an instantaneous mpg gauge (which I used to mentally calculate the load from), I realized that it is really easy to step too hard on gas in 6th gear and run rich.

In a heavier car (for the gearing/torque), this can be a huge problem. Cruise control would make the car run rich up hills!

I still like tall gearing, but you definitely have to be on top of your shifting game and have a careful foot to get the best out of it.
