@MelonUsk97 the company has the size (market capitalization) because it is growing so dramatically. You can work out how "big" it would be if it were a normal car manufacturer (IT WOULD BE!!!! I don't want to twist some truths like you do, because of course it is growing considerably). But this bonus with the growth is included and that's why it's worth so much.
@MelonUsk97 none of the robots have been sold yet and as far as I know there is no real prototype yet. There's a nice video about it from Simplicissimus. You can take a look at it
