Why the peek makes sense
Nobody reads a message on their knee at fifty because they've weighed it up. They do it because the phone buzzed and the itch arrived and the road looked empty, and in that moment looking is the thing that makes the itch go away. It's worth being honest about what the peek gives you, because a habit that gave you nothing wouldn't have survived the adverts.
It gives you relief. The buzz opens a question, who is it and what do they want, and the peek closes it. The itch is uncomfortable in a small way and the peek ends it. It gives you a use for dead time. The drive is twenty minutes in which you can't do anything else, and the phone turns it into twenty minutes in which you can. It keeps you reachable, which matters if you have a job or children or a parent who might ring. It gives you the map when you need the map. And it gives you, every single time, the experience of nothing happening. You looked, you looked back up, the road was where it was. That last one is the strongest, and it's the one chapter 6 is about.
Underneath those there's a set of beliefs, and they're the chapters that follow. That a glance is nothing. That you only do it when it's safe, and you're the one who knows when that is. That you're a good driver and the risk is other people. That you've done it a thousand times. That hands-free is fine, or voice is fine, or it's no different from talking to a passenger. That the message might be urgent. That you'd stop if it were really dangerous. That it's only at the lights, and everyone does it anyway.
Each of those has something true in it. Most glances are short. You are, probably, a decent driver. You have done it a thousand times. And each of them is doing the same job, which is making the peek feel like a decision you've already thought about, when it's a thing your hand does when the phone lights up.
This book isn't going to tell you the itch isn't real. It's going to look at each belief, with the research where there is some, and then it's going to give you a way of driving where the itch doesn't get a vote, not because you've resolved to resist it but because the phone isn't where your hand can reach.
