I remember studying this in high school physics class. At the time, it kind of blew my mind but now it just seems completely intuitive and common sense to me but alas it’s not common at all. At best, you end up shaving a minute or two off your arrival time over medium distances. Over long distances (hundreds of miles) maybe 5-20 minutes. Is it worth it? Almost never. The things that impact arrival time the most are reducing stops and left turns (increasing average speed), and leaving earlier of course. Now I live in a Metro area and have stopped micro-optimizing my route entirely (because traffic makes that moot) and I’m almost 100% optimize my departure time.
