The Wall Street Journal just published a lengthy report detailing how Google convinced Nevada state assemblywoman Marilyn Dondero Loop, as well as other states’ transportation committees, to introduce legislation that would help legalize its driverless cars for streets.

“This will save taxpayers countless millions of dollars and revolutionize driving as we know it. No more being distracted, no more accidents, and not another DUI attorney again.”

The Mountain View, Calif.-based company persuaded lawmakers, according to The Wall Street Journal, with “demonstrations and rides in its exotic cars,” and it subsequently earned “legislative wins” in Nevada, California, and Florida. There are even bills pending before legislators in Hawaii, New Jersey, Oklahoma, and the District of Columbia:

In the process, the Mountain View, Calif., company is building its credentials as an astute political operator. Google has been “pretty savvy” at navigating state capitols, said Frank Douma, a transportation-policy author and associate director at the University of Minnesota’s Humphrey School of Public Affairs. With its self-driving cars, Google “knew what they were doing by moving forward in Nevada” before approaching bigger states, he said. “If you blow it in the first state, you’ve really got problems.”

Success at legalizing self-driving car technology has broader implications for Google. Skills learned from lobbying state lawmakers could aid other endeavors that will require local policy-making, including the potential expansion of its Google Fiber Internet and TV service into markets dominated by cable companies.

Google spent roughly $9 million during the first and second quarters of 2012 lobbying in Washington and coaxing lawmakers and U.S. Department of Transportation officials, but Google did not disclose how much went toward lobbying state officials.

The Wall Street Journal also posted an interesting video (above) that briefly describes how Google’s driverless cars gather data to enable autonomous driving. A “spinning laser device,” for instance, sits atop the car and sprays 1.5 billion beams per second in all directions, while a radar sensor on the front grill tracks movement up to 650 feet around the car. The video also gives a closer look at one of the space-age cars as it roamed through the San Francisco Bay area.
