Why would a camera force this regulation when every car already has a ... speedometer?

They have your speed, where you began and where you were going. Way more damning.
In the states, there's rampant violation of vehicle-related laws and minimal enforcement (fake temporary tags, deliberate obstruction of real license plates, deeply tinted windshield and driver/passenger glass, not to mention rolling stops and speeding)
Modern cars record their speed today, no one bats an eye. Even before in-car tech could do this, you could passively enforce speeding by using toll booth data, but that doesn't happen. Neither side cares enough to bother.
Some EU countries do that on tollways but don't keep them always-on because they generate too many tickets to handle.
