This time of year it really gets my back up why so many drivers think it's OK to drive without lights on when 'regular' commuting time has that inbetweeny light, ie not light but not dark. Just because they can see, doesn't mean they can be seen!!!! And usually it's people with darker colour cars as well.
And never mind the cyclists who haven't got lights on their bike and they cycle on unlit country roads in the dark
