Not sure if this counts as promoting your post but in the interest of honesty.

You can't actually see stars in the Tesla cameras, they're too wide angle... (The opposite of zoom like a telescope would have to get far off lights.)

Those white things floating away from the car are ice crystals condensed off the thrusters...

That's why they always come from underneath.. never toward the car and don't match the rest of the background movement as the car rotates.
