One good point to make is that a rotating frame is not an inertial frame.
It is an accelerated frame, and one can determine by measurement... A ring
laser gyro of sufficient sensitivity can detect the rotation of the earth
as can simpler implements like foucault pendulums. An object's apparent
velocity only makes sense in an inertial frame.
