I've never even answered the phone while driving. And now there's a law saying I can't without a headset! Gee, too bad I'll never have that experience.
The closest I've got is glancing down at my caller ID to see who I have to call back
when I get to my destination.
And, of course, who can forget
my experience a year or so ago of taking a bus while the driver was texting and listening to his iPod in one ear...
