I get it frequently on my commute.
I use a major fast single carriageway NSL.
"Improved" with edge lines well in from the edge, and lots of double white lines and centre hatching (a lot of which have broken edge lines, but few people seem to know what that means anymore).
The actual carriageway is three to four lanes wide along most of it.
But that's no use when the cars coming the opposite way are pushed over to the centre, the cars going your way are pushed over to the centre, no one will do over 50, no one will overtake, and if you try, instread of moving out of the way, they continue between the lines, flashing their headlamps at you.
And now they are "improving" the road further by sticking in bollards and islands and reducing the approaches to roundabouts from two lanes to one.
Mind you, there is a set of traffic lights, with a two lane approach, still left.
Unfortunately, the "driver" who's been trundling along at 30 tends to take the right hand lane, especially if it's empty:
I was once behind a "driver" who did that, and like a fool I followed him, assuming that I would be able to get in front of one of couple of very heavy lorries, or at least the tractor, interspersed between the half dozen other vehicles in the left hand lane (that had been at the lights long before we got there).
Nope, half of them had got through the lights before he even started to move, and they all had before I got to them.
And they changed!
