I'd say it's probably harder to ecodrive an EV. The biggest controllable factors of efficiency are speed and cabin heat use.

I just watched an hour video on the Chevy Bolt Motor/transaxle. The one takeaway I learned is that shifting to N disables the electric oil pump that keeps the top mounted sump full of transmission/cooling fluid. I'm not sure if other EVs are built similarly, and I'm not sure if it matters much, but it's possible the gears don't get adequate protection while coasting. I might stop that habit in the Prius.

Skip to minute 9 through 10 to see an explanation of the lubrication system.
