I don't have kids so have no knowledge of when school term times are. However I can tell very easily just by how much traffic there is on my commute to work if the kids are at school or not.
School holiday = far less traffic. Fact. But what I don't understand is why?
People I know with kids don't take every day off work when the kids are off school - it'd be impossible unless they've got a massive holiday allowance compared to normal. They don't turn up later or anything either...
My commutes over the years have never passed a school so its not the actual "school run" I'm missing.
I can't compute the logic of why there are less cars on the road?
