Well we don’t own an EV/PHEV (yet), but we did test drive a few, and in each of them we set the regen to “high” as well. Just feels naturally if you’ve ever driven a lorry (engine brake).
Other than that, usually drive in “normal” for steering/throttle settings, all those modes do is just change the steering resistance and the throttle curve, unless you have an adaptive suspension. For most cars, it doesn’t make a difference between “Eco” and “Normal” in terms of fuel economy. The difference is simply pressing the accelerator 1cm instead of 2cm (arbitrary number), there’s no trickery in the background reducing consumption. It just helps to keep a “lighter throttle foot”.
Not sure where the difference in an EV to an ICE car is in terms of sat nav, seating etc.
edit: to prevent arguments, i know that cars are supposed to coast more in eco. It doesn’t make a difference though, at least not in VAG cars with cylinder deactivation.
