Pure economically driven decisions should win eventually.

For example we have once reduced the number of school buses from 4 to 3. 20% or 160 students come with a bus. That's 3 full buses or 4 not so full buses. It's important however, that every arriving student has a class right away. Otherwise he may want to come with a later bus, overcrowding it.

Just on time arriving of those students with just 3 buses was a logistical nightmare. But just a constrain for the digital evolution of the school schedule.

Another big saving is to eliminate the afternoon school shift. We have 2 such cases already evolved.
