I’ve got an old(ish) generation merc (w209) where it’s just off, auto, speed 1 and speed 2. To be fair the auto setting is pretty good, don’t think I’ve ever thought it’s going too fast or not enough. The same cannot be said for the same feature in any of the Audi, VW, or Honda cars I’ve had with the feature.
I’ve also had a few Peugeot’s and Citroen’s and they were totally hopeless.... but at least after you turned the ignition off you’d have to turn the wipers off and on again to re-activate the auto feature.
BMW’s usually work that way too.
