Gas prices on the rise in Phoenix and nationwide - but still unusually low

Compared to the great (housing and) oil bubble, gasoline prices are indeed unusually low. Prices are roughly half of what they were at the peak in 2008.

Compared to the great dotcom bubble gaining steam in 1998, gasoline prices are unusually high. Prices are roughly double what they were then, representing a roughly 4% per year annual increase.

Perhaps "unusual" is the new normal?
