OK so a massive tax hike to pay for it but how much coverage is the Tram network going to have? And is it a 24 hour service? What capacity should it have, how many people will need to travel at peek times?

If you want to cover everywhere and serve everyone when needed then you need a big network of trams that sync somewhat conveniently for passengers, due to the nature of the infrastructure this means you'll be running a lot of unused capacity most the time especially if usage patterns change.

This is why busses are more popular with transport authorities outside high volume consistent use routes, the bus routes in my area change regularly to match demand. There's also a considerable portion of journeys that are unsuitable for tram or bus, taking trash to the tip or collecting six small trees for example.

There are solutions to these issues but we need to be aware of the problems that need solving and work towards intermediary steps so transition is possible. What we build now should be working towards an integrated transit network that's able to evolve towards efficient and complete mass transit where and when appropriate. Trams have places they work really well, we should be identifying them and highlighting them, pushing for trams everywhere is a mistake though.
