单选题 Need a ride home for the holidays? Hitchhiking may have fallen out of favor, but a new form of ride sharing has emerged to replace it on—where else?—the Web. Today tens of thousands of Americans go online every month to stick a virtual thumb out in cyberspace, especially during holiday travel seasons.
Craigslist.org—the largest ride-sharing forum—expects to receive a 50% increase in requests from users hoping to catch a ride home for Thanksgiving dinner. And why not? As a mode of travel, it"s cheap, fuel efficient and relatively safe. Besides, says Jim Buckmaster, CEO of Craigslist, "it"s an adventure."
Ride sharing on Craigslist is basically an electronic version of the bulletin boards you find on most college campuses. People seeking rides say where they want to go, and drivers with room to spare arrange a place to meet. Craigslist, which requires no membership and charges no fee, fields 20,000 ride-sharing posts in a typical month, a number that swells to 30,000 during peak travel times.
To meet the growing demand, more than a dozen major ride-sharing sites have sprung up, many of them quite sophisticated.
At Carpoolworld.com you enter your destination, and the site spits out a list of registered users headed your way. Ridester.com, one of the fastest-growing sites with 11,000 unique users since August, will send you a text message when a potential match arises. It will also bit you with a $2 surcharge for each transaction and take 9.5% off the driver"s fee. How much arc those fees? That depends on what kind of deal you can strike.
Ride sharing generally affords more companionship than a train or bus trip. A disclaimer on eRideShare, corn reads, "While the American Automobile Association (AAA) encourages carpooling with someone you know, it warns against ride sharing when you don"t know who is behind the wheel.
Ride-sharing sites like Ridester have tried to alleviate safety concerns by requiring users to register and instituting a feedback system in which passengers can rate the quality of their driver. The site also offers an escrow account that holds a passenger"s carpooling fee until the transaction is completed. For now the best advice is the one your mother would give: Don"t get into a car with perfect strangers, and if their driving makes you uncomfortable, ask them to drop you at the nearest bus or train station.
