Same here. On the highway I only use propilot to eat/drink so I can take my hands off the wheel for spells. Else I don’t think I get quite the efficiency, and manual as you can prevent unnecessary regen and smooth the power draw a bit.

If you have the SV or SL keep the tires at 44 psi (max as permitted on sidewall).

Stay with packs of cars to limit drag a bit as the leaf is a bit chunkier then the 3 or Ionic.

Keep air on Auto as it lowers the draw on the battery.

Use Eco mode.
Yeah, that doesn't work. Unless you are within a few feet of the car in front of you, you are actually hurting your efficiency. Cars ahead of you create turbulence that hurts you. Depending on the size of the car in front of you, the "bad" zone is 10-30 feet behind them so you are much better off increasing your following distance.
I'm sure we can find articles and information to support either side of this debate. As an example, this https://www.treehugger.com/cars/draftin ... -work.html article suggests following a semi at 100 feet would gain you some improved efficiency. I know someone shared an article earlier that proposed using the cruise control with three lines distance set to save on energy as well. Although I wouldn't recommend that because drivers can be rather erratic in their driving, and I would instead suggest maintaining a safe distance yourself.

I often see articles that claim cruise control is better for fuel efficiency but I believe they're making quite a few assumptions on the terrain, drivers around you, traffic, etc that are likely more "ideal" than "realistic" in my opinion.
Mythbusters tested this scenario with a big-rig during one of their seasons long ago.

Their finding was that yes, following a big rig boosted your mpg. I see no reason why this wouldn't translate. You can dig up the episode but I recall they got a modest boost starting out at safe distances and then they pushed it to thoroughly unsafe distances and got a hell of a boost. You'd have to go watch the episode to get the actual numbers. But their finding was that it does indeed work.

I think you mean less unsafe distances

LOL

I don't remember, I'd have to go back to watch it again. With a computer driving, things would probably be perfectly safe. Unless it was HAL

Well, have to say the response was quite predictable. Its like a different version of the "kw = kwh" circle jerk. I won't even mention your use of "ionic"

Exhausting to say the least.

In any case, I have exceeded 240 miles on a charge on the highway at 55-70 for most (maybe save 10-15 miles of traffic and construction) of the route. Trucks, cars, tire pressure, phantom range below 1%, magic, whatever. It worked without any real stress and with out hitting VLB. If you face headwinds without some help, you will get less range or have to slow down dramatically. North-South routes have been more favorable than going west (east was fine) as wind is often in your face going west.

Make of it what you will.

I am inclined to brick my car one time just to end the controversy.

Hi, new to this forum, just doing some pre-reading before my probable Leaf purchase. Currently I have a Volt but I suffer psychological harm every time the ICE kicks in.
I've seen it proposed that lower acceleration getting up to highway speed will improve efficiency. From an kinetic energy perspective it should not matter. Is there some inefficiency in energy used when there is a higher power draw from the battery?
