Oh this is definitely false! Night is very concerning and is a problem for computer vision systems. During the day illumination is fairly consistent. Sure the sun moves around, but it's not a spotlight. At night, illumination varies a lot. A detector that works during the day may not work at all at night. This is no joke, there are papers that show dramatic performance losses for tasks like pedestrian detection at night. Cameras are worse at night. They need to be more sensitive which dramatically increases their noise. They may need to have longer exposures leading to blur, which is of course made worse if you are moving the camera. Headlights also don't provide the same visibility so your reactions must be faster. Reflections are a big problem too. Oncoming headlights are also an issue. Nighttime testing will be critical.
