I've imagined Elon, still connected to childhood sci-fi dystopian futures, would most certainly include some secret "God Mode" backdoor that only he knows...

So, in a future where Tesla's are all over the roadways,and the earth falls under alien attack or some other crisis -- he could easily escape by speaking to any nearby Tesla, which would give him full access (maybe even unlocking faster speeds ;). Perhaps even having some sort of transponder to send the nearest Tesla's to his rescue, should that be required.

In the future where aliens land on Earth and start a ground assault[0], Elon can take all the Teslas left by fleeing civilians and use them as remotely controlled (soon to be autonomous) weapons to fight the invasion, all from the safety of his volcano lair. ;).

[0] - Why ground assault instead of orbital bombardment? Well, there aren't many alien vessels left in orbit after a massive onslaught of Falcon 9s and BFRs ;).

If I remember correctly, there is a scene in the book Daemon by Daniel Suarez where autonomous cars are used similarly.
