Hello @joseph1956
Road accidents have very high numbers precisely at night time, in my case I don't like to travel at night for some reason I avoid taking road at night. I did not know this concept of road hypnosis, but it makes a lot of sense as certainly our organism can show tiredness after a certain time behind the wheel.
Best regards, be well.
It is something little publicized, I do not understand the reason, because it should be part of a warning for drivers.
