TSLA: Just another car company

I used to cover the auto industry. Traditional multiple for automakers is 8x. Dogs like $General Motors(GM.US)$ are worth 5x. $Tesla(TSLA.US)$ currently trades at 40x, and that's after being down all year.
Even if you give $Tesla(TSLA.US)$ massive credit for FSD, EV innovation and AI, I still don't see how you can justify the stock trading more than 30x when companies like META trade at 32x.
Which is a long way of saying if deliveries are down again tomorrow, I expect the stock to take a dump. Maybe 20%.
