  Suppose it is a sweet yogurt and has 300 kcal in a package (1 kcal/ml) and we use bioethanol in a car, it is a match 1:1. Ignoring conversion losses and metabolism, a car taking 6l/100km and a trained human on foot would go some 12 km on this. (human on a bicycle is comparable to a specially designed ecocar) A fully manned car (5 persons) or a loaded truck wins by a good margin even over a tandem or cargo bike. A bus or truck even more so. The main difference is in initial material costs, refining metals is expensive. The problem remains how to cleanly burn and source bioethanol.
