Well, roughly every driving week or so...

Just two days ago, driving on a roundabout some lady enters the roundabout right in front of my car. Fortunately it was a two lane roundabout and the left lane was empty so I could swerve to avoid crashing into her left hand side door (I was coming straight at her).

At the traffic light I asked her if she had not seen me and she went 'Seen what? Where?', so apparently she had not seen me at all, which is pretty impressive given that I was less than 5 meters away from her when it happened.

This sort of thing happens with some regularity. All it takes for a situation like that to turn into an accident with possibly a fatality is for me also not to pay attention.
