My column today explained an upside of the corporations-are-people-too precedent: If corporations are claiming the rights of people, then people should start claiming the rights of corporations (including all the sweet tax breaks companies have carved out for themselves).

But there’s another possible perk of companies and people becoming indistinguishable: Maybe corporations can keep you company (no pun intended) in the H.O.V. lane. From the Pacific Sun, last year:

[Jonathan] Frieman was contesting his $478 carpool lane violation on the grounds that while driving south through the two-passenger lane in Novato last October, a set of incorporating documents constituted a second person in the vehicle — if the U.S. Supreme Court grants corporations the same free speech rights as citizens, as it seemed to in the 2010 Citizens United ruling, argued Frieman, then he and his corporation papers count as two people in the carpool lane.

According to a press release from Kathleen Russell Consulting, the Mill Valley-based firm handling publicity for Frieman’s quest for justice, state vehicle code 470’s definition of a person includes “natural persons and corporations.”

Frieman has vowed to appeal the case all the way to the Supreme Court “in an effort to expose the impracticality of corporate personhood.”

You can find more on Frieman, the self-titled “Carpool Guy” activist, on his Web site.
