My experience of driving in Phoenix these past 12 years - our streets are unbent by lake or stream so we have a near perfect grid throughout the whole city -

I have always left a stoplight quickly and reached the speed limit very rapidly, probably around 90% throttle and shifted in the low 4k's ... then when I reach the posted speed limit I stop accelerating and maintain that speed.

I am apparently the only human being in Arizona who does that, because no matter what car I drive, how low its horsepower, I pull out WAY ahead of everyone else and much later, when I've reached the 45mph speed limit and settled there for quite some time, all the people I left behind blast past me at 55-60mph, only to stop again at the next light and repeat the process.

I don't do any "hypermiling", I simply get up to the speed limit quickly and then stay at one speed until it's time to stop. I consistently get higher than the EPA mileage on whatever vehicle I drive.
