Does anyone remember the trajectory of Elon Musk's space Tesla car?
I just realized that if that thing manages to leave the solar system, it could unironically be the most easily detectable (by aliens), interstellar probe that humanity has ever launched.
And if an intelligent alien species does get their hands on it, they might learn more about humanity from studying that car, than from a bullshit gold plated "vinyl" disc. (I'm looking at you Voyager probes).

(I would laugh my ass off if the play toy of a capitalist got us to make contact with intelligent life out there and not the efforts of government funded NASA).
