Ideally some 'low light camera' should warn you that in darkness far ahead there's 'something' unusual on the road and you will have time to react. Recently there was accident where truck with palm oil overturned on highway and first cars crashed into the truck because they were travelling too fast and only with low beam lights : https://www.youtube.com/watch?v=igX765Vw1fY

For example this camera module will be used soon in cars and it's really more sensitive than driver's eye : http://www.camera-module.com/download/sony-imx390-sensor-sel...

Adding thermal imaging to the sensor suite would probably help with a lot of edge cases, but the hardware is still very expensive. It has come down some in the last 5-10 years but there is a long way to go.

The necessary sensors are really expensive, and that's why the production cars from Tesla and GM and such just aren't that great at it.
