On one hand, this doesn't seem like a lot - at least it's fairly insignificant compared to what the average North American puts into her car. The average commuter might reasonably burn 10 times as much gasoline than this in her car each week. On the other hand, when you think about how much heavier and therefore harder to move cars are than people, 33km is looking pretty good. It's clear that cars are making much better use of fossil fuels than humans are. So maybe we should stop "eating" fossil fuel energy and just feed it to our cars and other machines. That would make living difficult though, wouldn't it? And besides, aren't the machines just there to make life better/easier for us in the first place?
(Follow-up Bayblab bonus homework: With the manufacturing processes in use right now, how much ethanol fuel can you get out of the grain in a box of 2kg cereal? How far could you drive that 2008 Honda civic on this ethanol? How much additional fossil fuel input is needed to convert the cereal grain into ethanol? How far could you drive a Honda civic on that extra fossil fuel?)
