President Barack Obama hasn't had to drive himself around for years. And he may not have to after he leaves office either. Obama Monday threw his weight behind self-driving cars -- as long as they're safe. His op-ed in the Pittsburgh Post-Gazette, which will appear in Tuesday's print editions, lauds American innovation and comes just a day after Lyft CEO John Zimmer predicted the end of individual vehicle ownership and a week after Uber began an autonomous vehicle experiment in Pittsburgh. "The progress we've seen in automated vehicles over the past several years shows what our country is capable of when our engineers and entrepreneurs, our scientists and our students – backed by federal and private investment – pour their best work and brightest ideas toward a big, bold goal," Obama said.
