For anyone thinking they can just cover it or something...
Those cameras are for detecting distracted and tired drivers. They run special AI models that track eye movent and other queues. Covering them will obviously be detected by so will be putting a picture in front of it.
When it detects it's disabled a warning light will light on the dashboard. For now it's not specifically forbidden to cover it but the warning light may mean issues when passing technical revisions. In case of an accident insurance may also treat it as a proof that you were at fault. For now it's all just speculation as the rules are new but most likely it will go this way.
