If it rains today, remember to turn on our headlights when using your windshield wipers. Congratulations to Evelyn Berk of Menlo Park, who won Joe Simitian's "Oughta Be a Law" contest by submitting the idea. Next time we get pulled over, we'll think of you, Evelyn.I remember this bill. Pretty logical. Commuting in perpetually socked-in San Francisco, I'm consistently floored by the number of drivers who just don't mind being completely invisible during fog and rain. Duh.
