evidence: Gas prices were already expected to breach the $4 a gallon mark for the first time since 2008, with or without shots fired in Eastern Europe or economic sanctions imposed on Russia. [...] More than one out of every five gas stations nationwide is now charging more than $5 a gallon for regular, and just more than half are charging $4.75. There are 10 states, plus Washington, DC, where the average price is already at $5 or more: Alaska, Arizona, California, Hawaii, Indiana, Michigan, Illinois, Nevada, Oregon and Washington. Several more are within a penny of $5, so those states’ prices are likely only a day or two at most from crossing the mark.
