The cameras can and do detect if a sign isn&#x27;t stationary, etc.<p>For speed limits, the obvious technical problem is knowing when they end, if they apply to your road, or maybe a parallel road or an off-ramp, which is mostly easy for a human to tell, but much harder for a camera.<p>Even though the camera may be better on average processing all this information than the average human driver, it&#x27;s an unanswered question, from a legal point of view, who&#x27;s responsible when the camera is wrong.<p>Volvo has recently taking a stand proclaiming legal responsibility, but it remains to be seen if that&#x27;s even a possibility in many nations.
