The problem with touchless car washes is not the pressure but it's the chemicals they use. They are pretty harsh and will strip your wax protection after a couple of washes then they can start working on the paint itself. Most of them do have cycles where they have conditioners and surface protectants that help but it will still eventually break your wax down. I do use them though when I just need to touch the car up a little. The good thing is the touchless will not swirl the paint on a black car like the brush washes do. As long as you keep up on your wax, touchless should be fine but still, nothing beats a good hand washing if the car is really dirty.
