The sensor in the motor is used for commutation. You can't commutate a motor with a sensor located on a geared-down gearbox shaft.

I would be likely adding my own sensor regardless of the type used.
If the motor has a sensor you don't need an external sensor. You can know vehicle position and velocity by counting motor commutations (unless it's all done in hardware and hidden from you).
