How strong are the motors in these devices? Could an attacker boost the power to full and cause injury (tearing of sensitive tissues?)
Could an attacker cause the device to draw too much power from the battery and overheat, perhaps by exploiting a flaw in the hardware through the vulnerability in the networking?
Suppose someone with one of these devices was crossing the road (with the device off.) What if the sudden activation of the device distracted them to the point they were not able to cross the road in time to avoid being struck by a car?
