I use an automated wash at my local Costco, and it even has those foam "brush" things. I am a terrible person. The biggest thing is getting aligned right to not scratch your rims on the tracks, then just put it in neutral and stay seated in the car.
I do NOT use the kind of washes where they send your car through without someone in it - then the car has to be in tow mode, and that sounds like a nightmare if someone messes it up. So I just use the Costco wash and call it good. (I do have a full PPF wrap, tho)
