I found an article entitled "Bizarre, Metallic Star Spotted Hurtling Out of the Milky Way at 2 Million Miles an Hour". Please see the following URL:

That does indeed qualify as something scooting along at extreme speed, but that number prompted doing a little arithmetic.
This object is approximately 2000 light years away which on a galactic scale, makes it one of our galactic neighbors.
At two million miles per hour, it is travelling at well above this galaxy's escape velocity which means it's saying bye-bye to us. However, if we look at how long this object would take to traverse the equivalent of the distance from here to Alpha Centauri, our closest interstellar neighbor, that time comes out to be more than fourteen centuries.
In short, this metallic star may be "hurtling out of the Milky Way", but it is still going to be in the galactic neighborhood for a very long time, at least on a human time scale.
Fast is fast, yes, but the galaxy and the observable universe are BIG!!
