Electric vehicles are popular, but charging them remains a challenge

Rising prices at the gas pump are leading more consumers to consider electric vehicles in hopes of saving on monthly bills. 

Today, a gallon of gas across the U.S. costs $4.14, up $1.25 compared to one year ago, leading to higher monthly expenses for families who rely on their cars to get around. 

Improvements in electric vehicle technology coupled with sticker shock at the pump have led the U.S. to "an extraordinary moment in time" for electric vehicle adoption, one expert told CBS News.
