Round trip, so it was 25km. Sadly Peth Australia has one of the largest urban sprawls on the planet so 25km isn't an unreasonable commute here and when you are a young uni student sometimes it's more cost effective overall to live with your parents. This isn't a post in support of cars, it's more saying that fuel for bicycles is most certainly not free and to suggest it is is disingenuous. Arguably there may have been other things my friend could have done to reduce his food bill, but he was already pretty thrifty in general.

Well he certainly wasn't majoring in wilful ignorance so that probably works in his favour.

No it was the increase in petrol cost was less when he drove than his increase in food cost when he rode, he ate fine when he drove

I think public transport at the time was a real screw around for him because his area was poorly serviced and the nearest train station was super dodgy
