Chevy Aveo: How to improve CITY MPG?

I'm not sure whether it does or not. I do have a Scan gauge and the only time I've ever seen it read "9999" is during coasting while in gear at highway speeds. Of course, that's when the TC is in lockup and I wouldn't attempt coasting with it in neutral then anyway. It does get 37 MPG when in lockup mode. But the catch is that all our suburban roads have a speed limit of 30 or 40 MPH at most. On a typical Japanese car with an A/T the TC will lockup by 40. But not on the Aveo. Chevy screwed us with the city FE by the way they programmed the tranny. The best we ever get is 24 MPG in all city driving.

Nearly all our driving is done at speeds below 45 MPH, meaning the TC is not in lockup mode. I have never seen the SG read that high at these lower speeds. But I do get better MPG figures by coasting in neutral to a stop sign than I do with leaving it in drive.

I couldn't care less about wear to the brakes. There is literally a stop sign on virtually every corner here and brake life is minimal anyway, due to that unavoidable circumstance.
