I didn't report on our ride from 2 days ago.
Jan and I got the tandem out. Within 200 yards of home there is a pelican (or whatever) crossing. The lights changed and Arsehole Van Driver decided that overtaking us in the last 50 yards and then cutting in front of us was a Good Thing to Do.
That crossing is on a bridge over the railway and I normally use the downhill to get up to about 20 - 25 mph and then take the lane before the roundabout to come, in which the left lane is left turn only and the right lane is right and straight on. Because we were further over to the left than I would normally be, thanks to AVD mentioned above, lots more traffic passed us, all of it too close. As we were approaching the roundabout I did manage to take the lane again, preparatory to going straight on (ie RH lane once the lane divided).
We had just got onto the roundabout when the Merc driver behind us decided that now would be a good time to undertake us, and it was at that point, just as Jan signalled left, that she gave us a cheery wave as if to say "There's good pensioners, out for your daily exercise!" I'm afraid that at that point Father Christmas turned into something altogether more hostile as I bellowed "You stupid bag! You're in the wrong lane!" (I'm afraid in moments of extreme stress like this I find it hard to choose the correct vocabulary). She hammered her brakes on, fortunately, but it was close.
Just after we left the roundabout, very shaken by the last few hundred yards, she overtook correctly. It took us quite some time for the adrenaline rush to wear off.
