What I notice from the above is the lack of regenerated energy. You now drive a power plant, and utilizing that feature will aid you in getting more from the vehicle.
Driving higher speed is what an ICE excells at, but not an EV. The reason for this is obvious, but I like to explain it so forgive if this is already something you know.
ICEs use most of the energy for heat production, so the shorter time you drive them, in some ways, the less fuel you use. (Hence why the higher MPG for highway over city) Most ICEs are less than 25% efficient at moving you down the road, and many use only about 15% of the fuel to move the vehicle. So when you are hypermiling in an ICE, you can only save fuel in that 15 - 25% area. A few more miles per gallon by going slower, as much as ten if the vehicle is aerodynamic. Heat however is free!
With the Leaf all power is used toward what you want. You want heat, it will deplete the battery. You want speed, you will deplete the battery. You want to go long distance? Slow down and gain some energy where you can. Coasting in N is what I call free miles. Where I live I can get a lot of those even at freeway speeds. Going uphill or high speeds will require high energy use, and if it is in the 40KW range, you only have 1/2 hour of driving. (20kwh usable energy in a fully charged Leaf)
So keep that in mind and play with the energy use screen. I tend to jackrabbit away from stops using 60KW to get the car rolling but for only a second or two (Equates to using 10kw for six or twelve seconds, but loses less to resistance). With that initial punch I can then usually go into N and coast to the next light. I can then regen if there is traffic, or put it back in D to give it another little push if needed. If you drive slow you might use less energy, but you also might not have the time to gain any since you are still getting up to speed by the next light.
New drivers tend to use a constant draw (or regen) on the battery, which is fine, but not for getting the most out of the available kinetic energy. You don't want to gain energy except when you need to really slow down a lot. Many times coasting will slow the vehicle to keep you in the traffic flow. ICE's don't slow the way the EV does, so they often use the brakes where you can just use Eco or D.
This is a very different vehicle that they made to operate like any other. That doesn't mean you can't drive it like an EV. Explore the side roads and take time to enjoy the travel, rather than just rush to the destination. You can add miles to the trip if the speeds are lower. You can actually double your range if you can do a constant 35.
