So, you need to test what constant speed will give you vs P&G. If the difference is small enough, just start driving normal, and coasting with your engine off when you don't need any power (down hills, to red lights/stop signs, etc).
Wow. I start experimenting today for real, but it had not occurred to me that P&G might no longer be as useful. Very interesting.
See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
