PSA: please don't talk on your cell phone while driving!

Please note, those studies are for hands-free; nowadays, I see far too many drivers making bad turns while holding phones to ear.
@vfrmedia Hands-free is better than holding phone to ear, but ... yikes.
The worst I saw was a US driver in very heavy traffic (bumper-to-bumper) holding phone in one hand, lollipop in the other hand, using elbows on the steering wheel. This driver was also directly behind me, but traffic was too heavy for me to change lanes safely. At least I wasn't in an accident ...
The assumption of privacy within your car with the volume turned up also astounds me.
