It doesn't matter where our vantage point is. Yes, two objects moving away from each other at a constant velocity, in opposite directions, in classical physics at the speed of light would be 2c (v1+v2=2v). But this equation breaks down when we talk about relativity, and we get the following formula.
v = (v1+v2)/(1+v1*v2/c^2)
Now you see when velocity is low, it is very close to the v1+v2 formula. But as the velocities approach c, the limit goes to c.
