Modern automotive lidar systems operating at 905 nanometers wavelength were deliberately chosen to be invisible to the human eye, yet this same invisibility means the systems are completely blinded by sunlight in that narrow band, forcing manufacturers to add computational filters that attempt to distinguish between laser reflections and solar noise—a workaround so imperfect that autonomous vehicles still struggle with bright daylight driving despite being theoretically superior to human vision in other conditions.
