Nice hyperbole Peter.

The hole in the plate will only be Lorentz contracted by a factor of 10 if it is stationary. In other words in the stick's frame of reference, the plate will move past the stick. The plate (and the hole) are parallel to the direction of motion of the stick. From the sticks frame of reference the hole is moving in the direction of motion hence contraction of the hole is observed.

However in a collision scenario clearly the stick (or plate) is now travelling in an oblique pathway relative to the other. The plate is now no longer parallel to the direction of motion of the stick. Hence the plate and the hole do not undergoe contraction.

The report of the death of SR is rather premature.
