Obviously they are using some kind of algorithm to figure out if a device is attached. They would have attached a device, recorded the torque over time and compared with someone holding the wheel. Whatever difference they found, made it to the algo. As with any algo, there will be false positives.And I'm not convinced there's that much difference in the rotational torque caused by the arm having pivots compared with a free-hanging weight of similar mass.
I think they can do this as a retrofit. They need to make a wheel cover with sensors. The sensors can connect to the car by BT or some other method. They can offer it as an optional accessory (sold with a small margin), I'd buy it.The only non-crude method of detection would be to put proper capacitance sensors in the steering wheel.
It could also be a small attachment to the wheel with the sensor, rather than being a full wheel cover. Would need a way to charge, a small battery, a sensor and a tiny comms device.
