With Teslas now being mass produced, there are tons of non enthusiast owners who have no idea on maintaining paint. On the Tesla fb groups, most owners run their cars through automatic car washes regularly, non touchless at that and all say it has no ill effects. I'm not surprised since fb group members are not enthusiasts but I wanted to see what forum members think. I've been detailing cars for more than half my life and can guarantee you all automatic car washes sans touchless leave some sort of microscopic surface scratches.
