## The Density Dilemma in Logistics
The secret to Amazon's logistical dominance isn't necessarily faster vans; it's Route Density. 'Drop Size' (how many packages stay at one building) and 'Stops per Hour' dictate whether you survive in last-mile delivery.
### FAQ
**Q: Why do delivery apps struggle?**
A: A pizza delivery driver doing 3 stops an hour driving 10 miles total costs $15 in wages and $6 in fuel/wear. Total cost: $21. If they only charge $5 per delivery ($15 revenue), they burn $6 in cash every single hour they operate. You must either increase the delivery fee, increase stops per hour (batching orders), or lower wages.
