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 more people using them over the day.

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.

Anything less than 15 minutes means a time table is not needed. Have trains
every 5 mins and people will just hop on and off at will.
