Lady Leadfoot made an interesting comment on the up-coming hand-held cell phone ban today (she'd have posted a comment but - well, let's not go into her computer skills).
She mentioned that this legislation implies that as long as you're doing it hands-free, you're safe, which we all know - well, the government doesn't appear to know - is just as dangerous.
So probably some people who might have refrained from using their phones while driving will go get a Bluetooth headset, strap it on ("Do you want fries with that?") and go terrorize our roads even more than currently.
Ah, that old law of unintended consequences...
