I'm not sure I follow. Bright sunlight strongly triggers my wake response, even if I've only fallen asleep within the last hour or so. And even with blackout curtains or no windows, you'd still be starting your day long after the sun is up.

All I'm saying is that it feels psychologically rewarding (for me anyway!) to wake up and start the day before the sun is blazing. When the time changes in the winter, that perk is gone. Moreover, driving without sunlight in the morning doesn't seem like a big issue; it's presumably preferable to driving at night when ambient light will only decrease.

Excluding shift workers, I don't think I've ever heard someone complain about too much daylight during evening hours--aka the hours during which people are usually living and enjoying life.
