So people are ignoring this about car washes?

I assumed, because of this message, that the paint finish sucks and needs gentle treatment (i.e., maybe it doesn't have additives that harden the coat that also interferes with external sensors).
I recently took my S to a hand car wash and when applying the soap using a brush using a light touch trying to only have the foam touch the car. Despite that, my wife, two days later, found a mark on the car door (maybe from washing the car?). Or is it just a standard warning on all cars that if the car wash takes off a sensor or mirror that it's not covered by warranty? Did I over react to the Caution? The car washes that touch the car with the massaging rags look pretty harmless (no whirring brushes).
And on that mark on the side of the car ... should I try a buffer?
