In cities with working public transport it aligns the schedules to accommodate the ridership. Which sucks a bit in the late evening when headways might become a bit long.

The absolutely largest peak is in the morning and then a smaller one in the afternoon.

So you might have a baseline like every 10 or 15 mins and then in rush hour it is every 3 or 5 mins.

again. Stupid. Complete nonescense that comes from people who drive themselves and think of transit as for 'lesser people'.

humans have places to be. They shouldn't wait for transit. and they mostly won't.
