Oh, don't worry. The bowling ball "test" was made before they had a prototype

Remember that day when Elon had an event in a neighborhood, pointed to the house behind him, and said it had solar roof tiles? When he held up a piece of pretty glass roof and said it was a solar panel?

He lied. He stood up there with a piece of glass, and he straight up lied to our faces... He lied with fake tests, fake metrics, fake prototypes
