The first step is to put down some tempting food for the hog. He'll be wary at first. But eventually, his hunger will overcome his caution and he'll eat what's been left out for him. If you keep leaving it out for him, his laziness will will cause him to come looking for the food you leave.

The next step is to put up a section of fence just behind where you leave the food. At first, this will unsettle the hog; he will approach warily. But he's hungry and that soon overcomes his wariness and he pays the section of fence no more mind.

You can probably guess the next step. Another section of fence at a right angle to the first section. Then another on the other side, also at a right angle to the first. The pen is complete when the last section – the gate – comes down and the wild hog is now supper.

I got to thinking about the hog as I sat in the 2024 Volvo XC40 Recharge that got dropped off the other day for me to test drive and review. At first, I could not figure out how to test drive it – because I could not find the start button. I soon figured out why.

There isn't one.

The XC40 just starts – more finely, automatically turns itself on – as soon as you get in and sit down. More finely, as soon as the Volvo senses it's you. All you have to do is put it in Drive – and off you go.

It also automatically turns itself off when you park and leave it.

This is the next step following the one that got people used to not having to insert a key into a lock in order to start the engine. Instead, people got used to carrying around an electronic transmitter fob that they didn't have to take out of their pocket or purse. All they had to do was push a button to start the engine.

Now they don't even have to do that.

As people get used to that, they'll be ready for the next and last step, which will be the elimination of the transmitter fob you still have to carry around in your pocket or purse – such a bother!
