Perhaps. I hadn't considered that. I guess there's just a part of me that envisions a bright future for humanity that includes a more mature culture that isn't as concerned with material possessions. Kinda like a Star Trek world. Ah well. I'm sure it's extremely unlikely and the SpaceX engineers took this into account, but I hope the Tesla doesn't do something we don't expect, like ram into Mars and contaminate it with Earth-borne bacteria. :/
