EVs could coast if a manufacturer chose to make one that allowed that without shifting into neutral. In practice, when letting off the accelerator, existing EVs will instead regen brake.

EVs could coast if a manufacturer chose to make one that allowed that without shifting into neutral. In practice, when letting off the accelerator, existing EVs will instead regen brake.
The default setting just moves the coast point to a slightly depressed accelerator. This is because EVs typically have lower drag, so this behavior mimics a higher drag vehicle. If you use the accelerator to achieve the desired speed, you will coast when possible. You can also monitor the display to see the coast point. My 2013 plug in hybrid only supports this style of operation.
Modern EVs have easy adjustment for this. The Hyundai/Kia EVs for example have shift style paddles for adjusting this on the fly which includes a mode for regen only when depressing the break pedal.
The Hyundai/Kia EVs do not have a mode that only regens when pressing the brake. The best you can do is limit the car to 2kW of regen braking when not touching the accelerator. You can't disable it entirely.
It's true though that using this mode will extend the life of your tires.
People driving an EV learn, in a matter of minutes, to coast by just applying the right amount of pressure on the "gas" pedal.
They learn to sort of coast. The car feels like it's coasting. Sure.
Next time you do this keep an eye on the actual power readout. See if it's actually zero or if it's reporting ~3kW of braking or accelerating.
It hovers depending on how my foot modulates the speed. I don't want or need "exactly zero power readout", I only need to reach my target speed at my target spot on the highway, without having to action the physical brakes at any time.
Whether that is more or less efficient than a zero-power coast followed by some kind of braking exactly at the end... I assume the difference is so tiny that it makes no difference.
