What on earth are you talking about? Who wants a stinky car they need to pick parts off the car wash when they fall off?
When mobility is a service you use via an app on your phone, it will be 100x more convenient than having to maintain a car yourself. Tap, and the robotaxi arrives in 5 minutes. Leave the car without having to care where to park. You won't be around when the car is in the car wash. It will go there by itself. And if something falls off, Tesla will deal with it, not you.
