Otherworld Isekai Service

After getting killed in an accident, Diesel was in queue for reincarnation. Due to a careless mistake by an overworked Kami-sama, he ended up awakening in the body of something cold and mechanical. He found himself wrapped up in a mysterious service that whisks people off to other worlds... via being run over by divine trucks. Forced to live on as a truck until he collects enough karma, what strange experiences will he come upon?
