I love the PT Wellington does have, and am glad it's there but calling it great and implying its all fine and not in need of a significant upgrade is imo an enormous stretch.

There are very regular bus replacements at the moment, they shut down when the tracks heat up, the jville line is massively speed limited, services are infrequent out of commuting times and the whole system is geared to getting people into town. It's not a service many people can rely on for most of their trips and it forces people to drive and create the traffic you complain about. And that's not even getting into the buses.
