I don't get the message you are trying to convey. It's natural that Tesla is smaller than the largest automakers. It's smaller than medium automakers. That much is expectable.

If you are referring to the disconnect between revenue and market cap, it may point to a valuation error by the market. Or not. The market is clearly incorporating expected growth into the current value. Is the valuation correct? I have no idea. I'd not infer too much from this fact alone, though.
