idiot

Given any achievable velocities V1 and V2 and any finite lightspeed,
Lorentz invariance requires the bound on the relative velocities of V1
and V2 as viewed by any inertial observer in 1 or 2 cannot exceed

(V1 + V2)/[1 +(V1)(V2)/c^2]

This is transformation of velocities parallel to the direction of
motion.  For velocities at an arbitrary angle theta,

u_parallel = (u'_parallel + v)/(1+(v dot u')/c^2)
u_perp = u'_perp/(gamma_v(1+(v dot u')/c^2))
