Isn't it also the incorporation of metrics into the delivery drivers schedules? As in, those trucks have been heavily wired with remote telemetry for everything, all of which goes to the local regional managers.

Who get told "we need an X% increase in productivity" - so they look at their metrics and come up with some idiot conclusion like "drivers just need to spend on average X seconds less per delivery...so I'm going to start measuring people by how long they're stopped making a delivery and have reviews when they are stopped too long".

Meanwhile, the delivery driver who has a route full of apartment buildings without easy truck access gets screwed.
