Phones in cars, BAD
It's kinda old news, but it's in the news again, and it's no surprise ...
From this article referencing the Journal of Experimental Psychology: Applied
handsfree mobile phones are just as distracting as handheld models
chatting on a mobile phone can slow the reaction times of young adult drivers to levels seen among senior citizens, and shown that drivers using mobile telephones are as impaired as drivers who are legally drunk.
So stay off the phone when driving!
