Another quick note...
It upsets me if people (when they are driving a car) change lane while making a turn on an intersection or at a round about. For example, somebody makes turn from the outer lane but while turning, this guy also switch to inner lane cutting every body in the inner lane. First of all, hello, we are not in F1 track, so don't practice your racing line* on public streets. Secondly, those lane markers are made for a purpose, ie to avoid collision. Thirdly, guys, nobody likes being cut in the street, so drive responsibly.
*the shortest distance to go through a track
Just for illustration, below are the right way to negotiate a turn at a round about, please also note when and how we should indicate the turn signal correctly, courtesy of NZ transport agency :
