Notwithstanding the fact that a typical visible light imager in a driver assistance system alternates exposure times between frames, especially at night: one over-exposed image to discern dark texture, and one under-exposed image to find the color of point light sources, such as traffic or brake lights.

The released video looks like the latter, though it could also just be standalone dashcam footage. It is also pretty mangled by compression, especially the dark parts are just completely blocky, so it is probably not a good indicator of what the vehicle saw.

OTOH, bikes can be notoriously hard on image recognition, for example it is not unheard of that reflective rims are interpreted as continuation of a curb or lane marking. LIDAR and RADAR should see them, though, and they probably did, so it is indeed unclear where it all went wrong.
