A current law bans anything from be affixed to the windshield (with few exceptions) or dashboard. Senator Jenny Oropeza has introduced Senate Bill 1567, the GPS Windshield Safety Act, which allow drivers to mount their devices on their windshields without fear of citation and out of reach of any restless back-seat toddler. So far so good: "Editors at several newspapers, including the Torrance Daily Breeze and the Long Beach Press-Telegram, have given it their stamp of approval. And both houses of the Legislature on Aug. 4 overwhelmingly approved the bill with broad bipartisan support." Now, on to the governor.

Corrections made 8/12. Source above cites Oropreza as author of the article and the bill and an Assembly member. She is, per comment, a State Senator. Her website confirms that.
