There is no "extraordinarily greater" speed in either frame.  This
is true in Galilean motion also.  Galileo described it perfectly
with his ship and dock example and blows your assertion out of the
water, so to speak.

It took years to find them, and without Poincaré, it is likely that they

had them in 1904.

That is why I am almost certain that Einstein copied them from Poincaré
despite his period denials (which he would later contradict by saying
that he had read Poincaré and that he had been captivated by the
intellectual
power of this man, considered the best mathematician in the world at
that time).

If Einstein copied Poincaré, then Einstein's equations are Poincaré's.

What does Poincaré say?

If an observer moves towards me, at speed Vo=v, and crosses me at
position 0, then for me, he is at (0,0,0,0) and for him, I am at
(0,0,0,0).
Not necessarily. "Position 0" is insufficient  for being at (0,0,0,0).

But let's assume that it is only a piece of rod 9 cm long
that crosses me, and that the other end has not yet passed.
At what distance will I see the other end of the rod? Let Vo = 0.8c.
You are going off on a tangent, not sticking to the problem you posed.
Furthermore, you haven't defined what you believe Poincaré's equations
are.  Consequently, your deflection is merely buzz words.
