I'm not going to lie. This ceramic coating sounds like a ball ache. Doesn't appear to provide any benefits and you still do the same wash routine but with extra caution to not contaminate the coating?
If you rinse your car correctly and have soft clean water then you shouldn't need to dry the car. I always leave mine to air dry.
I don’t think a ceramic coating’s for me. I enjoy polishing and waxing my car, and I’m ‘time rich’ (aka retired), so don’t find it a hardship spending time applying a couple of coats of wax every few months. With a ceramic coating, if you’re unfortunate enough to need and paintwork repairs, then presumably there’s also additional costs involved in getting the ceramic coating reapplied to the repainted areas.
As for not drying a car after washing it; unfortunately, not everyone lives in a soft water area. I don’t, and the water is very hard in my part of the country, so I always dry my car to avoid ending up with water spots. It’s sometimes a race against time in the summer getting it dried before the sun dries the water on as hard water spots - not a problem this time of year though. My warm air drier and supply of twin layer micro fibre drying towels are invaluable for getting finished before the sunshine does its worst!
