I think you need to distinguish the vector-space of velocities and

I'm pretty sure it's the vector space of velocities which defines the
vector space on the tangent space at each point on the manifold. If we
define addition as relativistic, it should restrict all those vectors
when added, to velocities less than light speed. Do you agree? AG
That's true of the vector space of velocities, but there's on such
restriction on the vector space of 4-vectors.
