Anecdotally, it's been a meme for years that everything Elon Musk does is about getting to Mars. Solar City? Mars needs solar. Tesla? ICE cars don't work on Mars. Hyperloop? Big vacuum chambers like that don't make sense on earth, but on Mars they might. Personally I'm highly skeptical of this narrative, but I've seen it expressed many times by different people going back years. I think a tweet like the above is Elon Musk playing into it, throwing some red meat to his most ardent fans.
