Cork crashes

I moved to cork from the west 5 months ago. I drive on the N40 from the city to ovens every day for work. The amount of crashes (not serious) I have seen in the space of 5 months is insane to me, I saw two tonight on my way home. The road is well laid out to my opinion. Is this down to people not concentrating or being distracted by phones. One evening before Christmas I saw three.
