Sensitivity peak for humans is in cyan (~510nm) only for low-light conditions (night vision / rod cells). In daylight (cone cells) it's green-yellow (555nm). h

>The eye behaves differently in high or low light conditions: in daylight, for brightness levels above 3 cd/m2 the vision is mainly done by the centre of the retina, we can see colors and the maximum sensitivity is at 555 nm (in the green region). This type of vision is called photopic vision. That's completely impossible, you would have severe tunnel vision in daylight, if it was true. There has never been any real evidence that rods stop working in daylight.

Here you can see that cones only extend to 2° from the center. I think it's illegal to drive with less than 20°FoV. https://www.google.com/search?client=ms-android-samsung-rvo1&hs=bIu9&sca_esv=6a0b219675808712&udm=2&fbs=ADc_l-aN0CWEZBOHjofHoaMMDiKpaEWjvZ2Py1XXV8d8KvlI3lB6BRmAv9Tdx4SvL4ZREsvAtO7uvBzcA2nI7Y2smQuOcOD1BRIJlYEP9L184wHplUnDJZldrEB9OrnQhro058BtHQi8SjOi7hgEVYTYNC4yFp6wV67XyBoBwgLNG_K6icd74SWNfqaojX3OWwqk_7UYMP03hPB86wRBy18I_YUyr-l_mg&q=cone+density&sa=X&ved=2ahUKEwijtcO2oKuSAxWfgP0HHYQhNR8QtKgLegQIEhAB&biw=411&bih=747&dpr=2.63&aic=0#sv=CAMSjQQahgQK4AEKuQEStgEKd0FNbjMteVN6LXZYYl80aFl1RWpSVGRDVXBlWjVGc3Jwbmp6NHFpNzdxTmVrRUNxd2oydHZDbkRwSERWLTlZay13T3I0Q0tNSU5OVDFSMXlpdnI4ZkVTZkpJQVhrbFFxMkRLdHpuM1pvRHFEbG8weHdJN0FTbG8wEhcyWEI0YWNMTkxwR0k3TllQb1BQR2lROBoiQUpLTEZtSkozUWVDdTMwN3J4ZDFqbnZQSkhjNHhacUVmQRIDODQ5GgEzIhEKAXESDGNvbmUgZGVuc2l0eSIHCgN0YnMSABKOAgrPARLMAQqMAUFNbjMteVMzSDkxb2doWGp6cTNCQ0dnVHVMdHFQOHpKSW0xYmVwemVnUE1IaEJISTRSeVhXNXVpQzdtMUZzUU8wMHBlY1hDZkZHYnFxdjMxZDY5ZHcyQUstTld1VzFtM1MzUm5WQ2hJNnJYbG4yRWFMdmVSS0JWc1dCdGNkelV5S2g3XzBGZUphb3ZqEhcyWEI0YWNMTkxwR0k3TllQb1BQR2lROBoiQUpLTEZtS0xYY19qbFNlaDU0UHFDY2ZnN1dIa3lZcnVrdxIENDY5OBoBMyIYCgZpbWdkaWkSDjJQRmxPUkVDRndhNnpNIhcKBWRvY2lkEg5FOXVack0xTEJWOURZTSoQZS0yUEZsT1JFQ0Z3YTZ6TSAEOAAYByCI_LfECDABSgoIARACGAIgAigC https://www.google.com/search?client=ms-android-samsung-rvo1...
