I don't think you should be directly comparing UPS and Amazon drivers in this instance. Amazon can pick and choose where they have contractors make deliveries (e.g. non rural areas with higher population densities). UPS serves almost everywhere. Additionally, we don't know what hours UPS drivers work in comparison to Amazon drivers.
