How many shippers are still not treating carriers well?  I think we are finding out that shippers who force long waits on their carriers or have big spikes in demand are learning that trucks are harder and more expensive to get. There are stories of spot market pricing being double contract rates and Canadian shippers paying round-trip miles.  And it is expected to get worse as volume picks up in April.  This is good news for us as  AutoO₂ (Automatic Order Optimization) drives increased load factor necessitating fewer trucks (one company is seeing a 10% improvement).
