Well, each price increment makes a dent first at the lower income level... and then works its way up the income scale. Obviously the price hasn't started enough to bite in your personal situation.

You will see it... nationally... and then personally.

I believe in the U.S. spending on transportation consumes 15 to 20 percent of the family budget. There is a limit at which people begin to travel less.

I understand the enough-is-enough factor; I'm just curious what the "limit" in Australia might be and if we ever get there any time soon... Or does it all just stop! (The long, slowly declining plateau to the cliff scenario).
