Or it would lower costs because saving gas saves money.

Increasing the transportation time by 30% has costs throughout the supply chain that greatly exceed the small difference in fuel costs. They aren't even on the same scale. That latency directly adds to the production cost of everything the trucks are carrying.

In my experience latency has near zero cost and if it has, just use air cargo. It's all about throughput and reliability.
