Route 96, on which these trams run, is every six minutes at peak

Half the size then they can run every 3 minutes.

Twice as many drivers required

But running large trains during the day mean infrequent services. Some
detach cars and run more frequent services.

If a rapid-transit urban railway has frequent services people use it

True: our airport express bus runs every ten minutes so you don't need a
timetable and there's a recognition that this is the ideal for trains,
trams and buses. But it would come at a cost.
