6．Well，parents，surprise!Lots of us are using Twitter and Facebook to thumb rides，and not just to school．It's awkward to be refused when you call a friend and ask for a ride．But with Twitter，you just look for other people heading the same way．
It may sound risky，so many teens stay within their own social circles to find rides，and don't branch out beyond friends when asking on Twitter just like me，but to some young people，especially those taking longer trips，stranger danger is less of a concern．
"I think the digital connection of young people is really key，because younger generations grew up sharing things on line，sharing files，photos，music，etc，so they've been very used to sharing，"said Juliet Schor，a sociology professor at Boston College．
The sharing economy got big during the recession （經(jīng)濟(jì)衰退），allowing people to access more goods，services using technology and even to share costs．And that technology，for me，is what the car was for my mom，a gateway to more freedom，like what my friend Earl says，"The symbol of freedom isn't the car any more because there's technology out there connecting you to a car．"
According to the researchers at the University of Michigan，30 years ago，eight in ten American 18-year-olds had a driver's license compared to six in ten today．So it's not that surprising that on my 16th birthday I wasn't rushing to get a license but an iPhone．
"Driving，for young people，does mean they have to disconnect from their technology，and that's a negative．So if they could sit in the passage side and still be connected，that's going to be a plus．"Schor continued．
To me，another plus is that ride sharing represents something，something much bigger than trying to save money．I see it as evidence that people still depend on each other．My generation shares their cars and apartments the way neighbors used to share cups of sugar．For the system to work，some of us still need our own cars．But until I get my own version of the silver Super Beetle，you can find me on Twitter．
