Do you think that driving standards have dropped over the last 10 odd years?

I used to ride years ago so got very good at driving defensively, after getting back on 2 wheels again recently I am constantly reminded of driver numptyness.

I had one driver on a 2 lane roundabout - while joining the roundabout opposite me - stay in the left/outer lane and indicate left/straight-on, only to continue round and turn right! I was right to wait.
Then this week on a dual carraigeway a car just drifted out into the right hand lane for no reason or indication?

Plenty of other examples but more aware and vulnerable to them now. A lot more texting and phoning going on as well.
