@aethernaut Example:

To start a car, you used to put a key in a keyhole and turn it. Which worked with all cars.

These days the key just has to be somewhere near the car, *with* a not-flat battery. OK, so that bit's easy to understand.

Then, somewhere, different in each car, there's a button or switch or something you have to flip or push or slide to start the engine. This button isn't always obvious, particularly in the dark, and even more particularly when it's hidden behind the steering wheel spoke.

And when you've found the button, of course it doesn't start the engine. Not until you've (a) got the car in the right gear, and (b) got the right set of pedals depressed, and (c) maybe done something with the handbrake, and (d) maybe done up the seat belt, and (e) maybe made sure all the doors are properly shut, and, for all I know (f) do something on an app.

Now ... these modern cars have a screen, right? Right in front of the driver? Which could actually *tell* you want you have to do to start the engine, yes?

And does this happen? In some cars yes, actually, jolly good; in some cars no; and in other cars the message telling you how to start the engine appears for a couple of seconds and is then replaced by an advertisement before you've noticed the message is there.

I claim that it wasn't my fault that I had to ask someone how to start a car for the first time yesterday, regardless of my age.
