Top 10 Cities For Car Sharing

PORTLAND, Ore. (TheStreet) -- Once again, America finds itself awash in $4-per-gallon gas with no fewer miles to commute, public transportation still catching up to demand and bicycles woefully inadequate for any but the most hardy individuals in locales with miles of bike path. Care to share a ride anybody?

As the latest Department of Energy numbers indicate, fuel prices have been inching steadily upward since early January and have hit a nationwide average of almost $3.80. Take it out to the West Coast and you're already looking at more than $4 a gallon.

Meanwhile, car use is slowly inching down as the days of $2 gas seem like a pipe dream and peak oil looks more imminent. The share of new cars being bought by Americans between 18 and 34 is down 30% in the past five years, according to auto pricing site Edmunds.com. A Pew Research Center study notes that people under 35 bought 12% fewer cars than they did in 2010.

Think it's just an economic anomaly? A remnant of the recession? Guess again. The Department of Transportation notes that just 28% of 16-year-olds had driver's licenses in 2010, with just 45% of 17-year-olds claiming the same. That's plummeted from 50% and 66% respectively in 1978.

Overall, as DC Streets Blog and the Frontier Group and the U.S. Public Interest Research Group Education Fund point out, Americans are driving roughly 6% fewer miles than they were in 2004. That's partially, as Census Bureau data shows, because more people are living in cities than they were a decade ago. It's also because fewer Americans want to put up with the $818 a year in lost time and gas money sucked away by the average commute, according to the Texas A&M Transportation Institute's Urban Mobility Report.
