My wife put something in my glovebox and It may have saved me from prison.

Let me be honest with you from the start. I am the last person who should be writing something like this. I think most gadgets are a waste of money, and I've never been one for fussing over the car. So when my wife slipped a little device into my glovebox months ago, I rolled my eyes and forgot all about it.

She's the cautious one in our house. Smoke alarms, the first-aid kit, the thing "just in case." I've spent forty years gently teasing her for it. And then one ordinary morning, the thing I'd never have bought for myself may well have kept me out of a prison cell.

I only ever looked at my tyres when the light came on.

I wasn't reckless. I want to be clear about that. I checked my tyres before a long journey, and I checked them when that little orange light appeared on the dashboard. The rest of the time, I left them.

If they needed air, I'd go to the petrol station. And if I'm honest, that was half the reason I put it off. You know the drill. Drive out of your way. Pay for air, of all things. Wrestle with a filthy hose. Get down by each wheel with a dodgy knee, hold it in place, squint at a gauge you can't read — and half the time you get there, the machine's out of order anyway.

So I didn't do it often. It felt like a chore, and it was.

The one thing I'd shrugged off.

Here's the part I never questioned: I never thought any of that made me a bad driver. Quite the opposite. In forty years I've never had an accident that was my fault. Not one. I genuinely believed I was one of the safest drivers on the road.

Nobody had ever sat me down and told me tyre pressure was a big deal. So I never treated it like one.

And the truth is, nobody had ever sat me down and told me tyre pressure was a big deal. So I never treated it like one. It simply wasn't something a careful man like me needed to worry about — or so I thought.

Then, on one perfectly ordinary morning, I found out how wrong I'd been.

What the police told me I'll never forget

I was driving through a quiet residential street. Not fast. A child ran out from between two parked cars — the way children do, in a heartbeat, with no warning at all. I braked as hard as I've ever braked in my life.

I stopped. But not quite in time. I caught the child a glancing knock. And thank God — I mean that with everything I have — the child was alright. Shaken, we all were, but alright. The mother, to her enormous credit, was the first to say her little one had run straight out.

When the police arrived they were thorough, as they should be. They checked three things above all else: whether I'd had a drink, my tyre tread, and my tyre pressure. I passed on the drink. My tread was fine. And my pressure — I scraped through. Only just.

Then the officer told me something I'd never heard in my life. He explained that for every 10°C change in temperature, a tyre's pressure moves by roughly one to two PSI. And that the friction of driving heats the air inside and adds another three to five PSI over the course of a journey.

My tyres had warmed up on the drive over. Had that morning been a few degrees colder, he said, they'd have started lower — and with how little margin I already had, I could very well have been looking at a charge of negligence. Same driver. Same street. Same child. A colder morning, half a PSI the wrong way, and my life would have been over too.

I sat there and couldn't stop thinking about it. One small thing. One thing I'd shrugged off for forty years. That's all it would have taken.

I fixed it there and then — and felt like a fool for waiting

Here's the part I still can't quite believe. Before they let me go, the officer asked me to bring my tyres up to the right pressure there and then. And I could — because sitting in my glovebox, put there by my wife months earlier and completely ignored by me, was that little device.

I pressed a button and watched it bring each tyre up to exactly the right pressure on its own. No forecourt. No hose. No coins. It was so easy it made me feel foolish. Forty years of avoiding a job that, it turns out, takes a couple of minutes on your own driveway or anywhere for that matter.

No kneeling, no straining, no forecourt

I'm not a technical man, so I'll tell you the way I understand it. You turn it on. You connect it to the tyre. You press the button and you walk away. It reaches the pressure you set and it stops itself — no standing over it, no bending down and holding anything in place.

That last part matters more than you'd think at my age. No kneeling on cold, hard ground. No strain on your back. Anyone can use it, whatever state your knees are in. And it's small enough to live in your glovebox, ready whenever you need it.

I'd recommend everyone to get one, but ask these questions first

I've since learned that these little pumps are not all the same, and I'd hate for you to waste your money on a bad one or worse one that you cant truly rely on. So here's what I'd ask before buying any of them — and why the one my wife chose turned out to be the right pick.

Is it actually powerful enough? Plenty of the cheap ones give up halfway through a car tyre. This one takes a car tyre from flat to full in minutes, and a quick top-up in seconds. It doesn't struggle and it doesn't quit.

What happens when the battery's flat the one time you need it? This was the question that won me over. It has a large 3900mAh battery that lasts months on normal checks and top-ups, so you're not forever charging it. But even if you've let it run down, it comes with a 12V lead — you simply run it from the cigarette-lighter socket in your car. A flat battery never leaves you stranded. To me, that's the whole point of carrying one. It should be ready when you need it most.

Will it still be working in six months, or is it the sort of thing that rattles and dies after one use? It's backed by a one-year warranty, the customer service is great and they have been around for years. It also comes with a set of tyre-pressure caps that change colour — green, to orange, to red — so you can tell at a glance if a tyre wants a look, without getting down on the ground at all.

And if it turns out not to be for you? There's a 90-day money-back guarantee. You try it for three months, and if you don't get on with it, you send it back. The decision costs you nothing.

But most importantly, the reason I my wife chose the AutoPump by Ordiniq is because every device is calibrated before it leaves the warehouse. This is what you dont get with cheaper alternatives on Amazon.

We should all be a little more cautious when safety is concerned

I check my tyres now. One, because I'm frightened but also because it's finally easy, and because I know now what I didn't know before. For once, I'm the one in our house who's prepared.

I was lucky. Somebody looked out for me before I even knew I needed looking out for. My wife's caution — the very thing I'd teased her about for forty years — is the reason I can still sleep at night. And I've come to think she was right about a great deal more than tyres. We should all be a little more cautious when it comes to safety, especially the small things we tell ourselves don't matter.

So I'm writing this for the other sceptics. The men like me who'd never buy it for themselves, and who haven't got someone at home who'll quietly do it for them.

If you'd like to see it, this is the exact one that was sitting in my glovebox. Consider me your cautious wife, for once. Check it out now.
