For most, high beams are passive. They require the driver’s interaction to go back and forth toggling manually. If a driver forgets, they can blind oncoming traffic very easily. It’s not just annoying. It’s potentially dangerous.
Volvo is developing Active High Beam Control, a combination of a sensor as well as light blocking mechanisms that know where cars are both in front as well as to the side. When a car is seen by the sensor, it blocks the high beams in that particular area without turning the high beams off altogether.
