Uber is bringing self-driving cars to Pittsburgh this month. Sort of.

For the past several years, Google and other companies have been testing out self-driving car technology on public roads. But if you were a member of the general public, there was no way for you to ride around in a self-driving car. Uber is about to change that. Later this month in Pittsburgh, the ride-hailing company will offer the first self-driving car service that's available to the general public. It represents a big step toward transforming self-driving cars from a research prototype into a commercial service.
