I'd be curious to see what kind of mileage you get, cruising at 80. The generalisation is that we're out for maximum range; that drops off rapidly when you keep the speed up.

I might touch 70 or so on my commute home, but that's on a downhill and feathering the throttle to keep out of regen. It would also be an interesting math question to see where the dollars fall: if time is money, is speed economical? At how many dollars per hour does more speed equal a savings?

I would need more/better instrumentation to record instant and average speeds and log those against fuel economy to be able to answer those.

Lead or follow. Either is fine.
