Warning: automatic car wash neutral setting
I think it works by the fact that the key fob remains inside the car the whole time. Perhaps something signals the car to allow the car to remain manually in neutral when it remains in the smart key slot. Seems like a nuisance to have to pull out the keyless go button.
or the parking pawl will cam over and over and over resulting in faint "click, click, click" while truck is moving in what feels like neutral.
on a somewhat related note many vehicles go through the car wash in park. the surfaces are wet and often soapy so the vehicle is just dragged with little drama with its driving wheels locked up.
