While it would be obviously a good idea it will not be do-able from a technological point... first, because such a detection, most likely with cameras, would need to always run even when the car is powered off. That means a lot of electricity being wasted. Second, because it will get abused by thieves - projecting, e.g. with a laser, something onto the cameras and boom, the windows open.

running over anyone is tragic, and i'm not trying to make light of it, but that's the same misapplication of risk, fear, and bias that lead to security theater, housing crises and regulatory capture generally.

we don't regulate for the people (US, annually) who accidentally drown in a bathtub (~300) and get injured in a bathroom (~250k), even though it would address more harms (at a larger scale and possibly greater cost, depending on the mitigations).
