Forget the incompetence of Kosky, DOT and KAMCO. Myki when it's finally working as proposed should be a good system. Like every other Melburnian I have my 2 cents on this issue. I think the system is needed, the old metcard although functional, won't be able to deliver a system that's repsonsive to Melbourne's needs into the future.
The main thing going for myki, and the whole point of it is tracking. The reason why they want us to sign in and sign off, is so they can find out where we're going, how many of us are using it, and where to put resources.
The system also paves the way for new innovate fare structures and a possiblity of direct refunds if there is consistant underperformance on the network (no more filling out useless forms!).
So let's get on with it. Test it live, and fix the problems as we go. That's the only way.
