At the New York Times, Farhad Manjoo wonders whether Uber, for all the very reasonable doubts about the service, could cause a serious decrease in private car ownership, which would have huge ramifications for not just transportation but also housing and environment. An excerpt:

“It is impossible to say whether Uber is worth the $17 billion its investors believe it to be; like any start-up, it could fail. But for all its flaws, Uber is anything but trivial. It could well transform transportation the way Amazon has altered shopping — by using slick, user-friendly software and mountains of data to completely reshape an existing market, ultimately making many modes of urban transportation cheaper, more flexible and more widely accessible to people across the income spectrum.

Uber could pull this off by accomplishing something that has long been seen as a pipe dream among transportation scholars: It has the potential to decrease private car ownership.

In its long-established markets, like San Francisco, using Uber every day is already arguably cheaper than owning a private car.”
