Just imagine how tragic it would be, if an ancient artifact of an alien civilization drifts by earth and we don't manage to have at least a look at it.
I hope one day we'll get a solar system wide observation network. Like the current arrays of radio dish observatories, but on a solar system scale.
'Oumuamua is red and headed toward Pegasus (the winged horse) after a very long journey starting longtime in spacetime ago. It is wildly tumbling off-kilter and potentially creating a magnetic field that would be useful for interplanetary spacetravel.
They're probably pointing us to somewhere else from somewhere else.
If this is any indication of the state of another civilization's advanced physics, and it missed us by a wide margin, they're probably laughing at our energy and water markets; and indicating that we should be focused on asteroid impact avoidance (and then we will really laugh about rockets and red electromagnetic kinetic energy machines and asteroid mining).
[We watch it fly by, heads all turning]
Maybe it would've been better to have put alone starman in the passenger seat or two starpeoples total?
Given the skull shape of October 2015 TB145  (due to return in November 2018),
maybe 'Oumuamua  is a pathology of Mars and an acknowledgement of our spacefaring intentions? Red, subsurface water, disrupted magnetic field.
In regards to a red, unshielded, earth vehicle floating in solar orbit with a suited anthropomorphic creature whose head is too big for the windshield:
"What happened here?"
