Coasting is a better use of energy than relying on regen if it does what you need.
It takes a certain amount of energy from the battery to get us moving. Coasting back down gives us the best range for the energy used, but slower average speed. It'll take some practice to get the feel for how far you can coast, so it's not going to return highest efficiency right from the start.
Some are suggesting we can 'find' a no-thrust and no regen point with the throttle - getting a feel for when the power is off but so is regen. A beginner can shift to N with little skill - it'll take a soft touch, familiarity, and awareness to find the zero-thrust point with the accelerator pedal.
If we're going downhill and need to keep our speed under control then by all means regen - it's much better than wasting the energy by using the brake. But regen isn't 100% efficient, so we don't get back all the energy we used to get us moving.
It's art and science - it might be an easy decision about when to transition from coasting to regen when traveling downhill, but the choice to coast uphill might be more challenging.
