Definitely not a misconfiguration. I had the exact same issue after a certain period of time with every fresh install. The solution was switching to Prezto / fish (work / home respectively).
I have some familiarity with the trucking industry in the midwest. I can also confirm that there's a shortage of drivers in the region.
The funny thing is that at some companies, working some overtime (although under the safety limit), drivers can make ~$80k including benefits, which is pretty good considering the cost of living there.
