Not only are drivers tired at 11:00p. cyclists are likely to be tired, too.
My experience is that many accidents take place when cyclists push the boundary of "prudent" - which of course has a wide range of definitions. Let me say, that in this case and in many others - the driver appears to be at fault. And I do not, in any way, imply otherwise. However, since cyclists are more likely to bear the brunt of any accident with motor vehicles, it is incumbent upon cyclists to err on the side of prudence.
Yes, there are times when I find myself behind schedule and pushing on after dark - but they are extremely rare. I also avoid riding on holiday weekends - when people are likely to be drinking. Add to that lakes and reservoirs with partying folks. Years ago I had a car towing a boat try to pass on a hill. There was almost a head-on collision and the boat went airborne over my head. as I was face down in the ditch.
