Tesla wont crash easily, it has a moat (the brand name "Tesla") and supportive customers who love electric innovative environmentally friendly cars, over the air frequent updates/improvements, and the future of autonomy, it also developed a strong storage battery business. Elon Musk is important but at this stage, Tesla could survive without him, he already built a solid band name, great already selling products (model s, x, 3) + so many models on the piepeline on advanced stage of developement (tesla semi, model y, new roadster). In worst case scenario he may now focus on spacex, the boring company or other endeavours. True Tesla kickstarted the electric vehicule revolution, but the movement now is well beyond tesla including demand for lithium from chinese EV companies or japanese EV companies (Nissan Leaf) or European EV companies (volkswagen). So I wouldnt worry.

Most likely Elon would be required by the SEC to step down as chairman of the board (almost certainly, its logical and positive for tesla IMO), they also want him to step down as a CEO (he is fighting this), time will tell if he stays as CEO in 2019 with this legal case against him from the SEC. But at this stage of Tesla, he is a big shareholder and would still have a say on the strategic future of the company. so not all is lost for him. as for Tesla the company not that worried.
