If you say that Apple has more relevant experience, then why doesn't Audi, BMW, Daimler, Ford, GM, Google, Kia, Mercedes-Benz, Nissan, Renault, Tesla, or Toyota beat them both? All of these have more relevant experience than either Google or Apple, because industrial design is not really what car is about.
I would say the chances of one of those companies you mentioned being more successful than both Apple and Google are extraordinarily high. Nothing in your statement conflicts with mine.
