Wellington is a pretty good place to ride in my experience. If you do the right thing then drivers are pretty courteous on the whole. But there is still plenty of work to do to smooth driver/rider/pedestrian relations and reduce the amount of conflict and aggro that still occur on a too-regular basis.
These PSA videos made by the Wellington City Council are a fun way to show that losing your shit because it took an extra three seconds out of your day to pass a cyclist, or let a fellow driver into traffic, is really not worth the stress or potential consequences. But the best bit is the cameo by noted Wellington bike nut Kah Hoe Chan grinding his way up Brooklyn Hill in civvies as if it were a mountain-top finish in the Tour de France!
