Yes. That was my question too.

A velocity change within the near field might produce a shrinking
wavelength as the velocity slows. How far does the near field extend
with an infinite wavelength?

I`ve heard of velocities greater than c, but these are relative. You
have incident and reflected waves on a transmission line and their
velocities, rekative to each other, usually exceed c. In space, c is so
reliable, we use it to measure distance.

Can we now challenge the radar speed traps?
