Here is one that will make you scratch your head. Despite a huge increase in the cost of gas since 1970, a new study by the University of Michigan showed that more people are driving alone. It's the latest reflection of how driving in America has changed over the last 43 years.
"We value the flexibility of driving alone more than the potential savings in the cost of gasoline," said Michael Syvak, Director of Sustainable Worldwide Transportation at the University of Michigan Transportation Research Institute. According to Syvak, the average number of people in vehicles has dropped from 1.9 in 1970 to 1.38 in 2010. A number of factors contributed to that change, including the growth of women entering the work force—so there are more American homes with two cars and two drivers heading to two different job locations.

In 1970 the average price for a gallon of gas was 36 cents. By 2010, the average price was $2.79 per gallon.
