Really?

According to the Washington Post, Maine is considering adding a warning about cancer risk to cell-phones. A state legislator claims that there are "numerous studies" to support such a risk. To be fair, I'm not really current with the literature, but I do wonder: do cell phones also come with a warning about risks of crashing your car?

For that matter, how about absolute risks of cancer, contrasted with absolute risk of crashing your car? Anyone seen these numbers?
