People like to whinge about the price of gas just as much as they do about the weather. This wouldn't be true if we all used our bikes to get where we were going, but I digress. Virtually every month I read a letter in our local automobile club magazine in which the author argues that the price of gas is fixed by colluding petroleum companies and that there should be a government inquiry into the matter. Some make a pathetic effort to support their annoyance, claiming things like "On my recent trip petrol (that's what they call it here) was $1.23/L in Tamworth and when I was in Brisbane only a few days later it was $1.18/L. Clearly this is a sign of price fixing." Upon reading that line of reasoning I was incredulous; hadn't the author ever noticed that the price of gas at their local station changes daily, if not hourly!
