It is a lot like driving with one hand verses two at the ten and two positions. Many people can safely drive with one hand but it is safer to be in the ten and two positions with two hands which is why we need to do it to pass most driving tests.
In theory (one, anyway) 10 and 2 are the best positions, so DMV examiners have been insisting on it.
In reality, it turns out, 9:30 and 3:30 are safer.
In theory, talking on the phone is distracting.
In reality, it's been shown that drivers who are a little bit tired are much safer if they're also talking.
In theory, texing bans will reduce traffic accidents.
In reality, people in those States text below the steering wheel, completely taking their eyes off the road, to avoid cops seeing then, while those in States without such bans tend to text with the phone at the top of the steering wheel, so they can at least keep half an eye on the road. Paradoxically, texting bans are deadly.
Tibbit's "solutions" work in theory, but reality is far more messy. To assume otherwise is hubristic.
