WebAutomatic high beams with proximity sensors on cars should be illegal. This technique just doesn't work properly yet. The high beams reach further than the sensors that detect oncoming traffic do. So you are still blinding upcoming traffic even though the technique promises not to do that. I don't get how this is legal. But I do agree very much ... WebApr 12, 2024 · Sensor or vehicle actuated systems depend on detectors embedded under the road or in the traffic light heads. Under the road, an inductive coil detects when there is a change in the magnetic field, such as when vehicles stop above it. Sensors embedded in the signal head work similarly, except they utilize lasers or cameras to detect vehicles.
