Voice texting is safer than calling. Calls are more distracting because there are real time interactions going on. If the interaction isn't required for what's being communicated, hand free texting is better. Is it needed? I guess not, in the same sense that a call isn't NEEDed. I mean we survived as a race a long time before bluetooth and cell phones.Do you honestly need to send a text message while driving? Yes, it's an advertised feature and you're paying for it, but still. If you really need to communicate, use the hands free and make a quick call.
