By your logic we should get rid of trucks and have all freight delivered by car.

My logic is trying to use the most efficient method to safely, efficiently, and affordably transport people. Deliveries are already scaled to the items they carry. No one is delivering a pizza in a semi-truck.

Which is what buses do. They are the lesser polluters, safe, efficient. For reasons unknown you are assuming buses are statistically empty when comparing them.
