My understanding is the relative velocities between macro sized objects in the universe are rather small. Small enough where relativistic effects are minute. The article mentions 3% the speed of light being the high end. You would be hard pressed to find anything larger then a particle moving 99% the speed of light relative to our sun. Even these hyper-velocity stars are only 33-50% the speed of light.
