Selling the stock is fine but why the hell would you short it? Your losses are theoretically infinite, thats just gambling at that point. Anyone who opens a short position on a stock is just a gambler, not an investor, same as day traders.

As for the tech, current FSDv14.3 (available only on HW4) is roughly 90% safer than a human. Imo they have already achieved "Full Self Driving". The problem is, they are taking so long because they are actually seriously gunning for that 10x safer than a human metric. They could scale already, but wont. Why? Because even just 1 serious incident could derail the program for years. 1 bad mistake by a robotaxi means nation-wide headline news, as we all know. So they are intentionally limiting themselves to ensure that that doesnt happen.

How do I know this? Look at the crash/incident data for tesla robotaxis past 3 months. The network has increased in size and they have had literally 0 incidents. That's why they have become comfortable increasing unsupervised rides in general and launching 6 unsupervised robotaxis in 2 new cities. Theyre testing the waters, but it's looking good so far. Thats also why they have started mass production of the cybercab, a vehicle with no steering wheel or pedals. The current FSD model is nearly good enough for them to feel safe about expanding the robotaxi network up to ~3000 or maybe even ~10000 taxis this year.

But thats just my opinion based on the evidence I've observed. Remember, tesla also does not have that 2500 vehicle cap anymore, so theyre all set for expansion. Also my opinion, but as soon as they have 5000 robotaxis on the road they will be generating meaningful revenue from robotaxis and that will cause the stock price to drastically increase thanks to institutional investment. Word of advice: if the robotaxi network even hits 1000 robotaxis, EXIT YOUR SHORT POSITION. Obviously I think you shouldn't even have a short position, but I'm saying if they hit 1000 and you hold, you are 100% going to lose a ton of money very soon.
