Not only is it very close to best efficiency, but it also creates the least disruption in traffic.

Agreed. In my 95 camry, when she was still alive, I managed to get about 29 average in the city. I found that whether I accelerated using 2750rpm and 2250rpm I got the same FE, mind you this was an automatic. I would honestly suggest testing. Because for me, accelerating using 3000rpm resulted in 24mpg, yet just 250rpm less resulted in 5 mpg more. I figure that anything over 2750 my car riches the mixture, causing more fuel to burn. I'm just talking out my ass, but it's a good estimated guess.
