Self-driving cars will be here before you know it.

Google announced in a blog post Friday that its first self-driving cars will hit the road this summer. They'll start out on the roads near Mountain View, California, the home of Google's headquarters. The cars have already been tested in Nevada as well as California.

Don't expect anything too fast or furious, though: Since the prototype cars lack airbags and other required safety features, they'll only travel 25 miles per hour, though the cars will include features that allow drivers to take control if anything goes wrong. Eventually, Google co-founder Sergey Brin says he hopes the cars will be able to eliminate the most common crash risk — human error — entirely, though he says there's still a ways to go before that happens.
