External Car Cover isn't Waterproof?

[Hoyamann]

I was under the impression that the outdoor car cover for the Model 3 would be waterproof. It does not do any good if it soaks through the rain, which is the case. Why isn't it waterproof?

They make 2 different car covers. One for inside and one of outside.

The outside one is waterproof.
