Oh yes not indicating of roundabouts is a
huge bugbear of mine too.
Also I would like to add.
Cowing middle laners,
people who ignore one way systems in car parks,
empty heads who park opposite junctions,
OAP vigilantes who pull out in front of you at the last moment in the utterly misguided belief their slowing you down when in reality their senile dessicated brains can't judge speeds that well any more
& lets not forget those oh so very special people who not only pull out in front of you at the last moment but make no attempt to get up to traffic speed but instead slowly turn left at the next junction!
All of these push me so close to going postal sometimes that I seriously consider tearing up my licence & sticking to shanks' pony.
