ELI5 How do automatic high beams work?

Question

My 2017 Toyota has a feature I’ve recently discovered that doesn’t just automatically turn my headlights on at night, but it will turn high beams on if I’m the only one on the road and will automatically turn them off when a car approaches – or even if I suddenly get behind another car. After observing for a bit, I’ve realized it’s scary accurate. How does this work?

Note: it doesn’t even turn them on if it’s just street lights, it seems to differentiate between street lights and headlights on cars.

Maybe sensors that detect other vehicles or mass bodies of metal??
