Why are you ignoring the load of the robot and the drivetrain itself? Even with your shifting coupler, it will only disengage as the motor attempts to turn the shaft the opposite direction. Until this is disengaged, as the motor slows the drivetrain slows, and the load of the drivetrain is placed on the motor.

CIMs do not "instantly" switch direction under zero load. Quickly, maybe, not instantly.
