Ok, I’m going to jump right into this. My husband and I rented a car to make our family vacation trip from Texas to Florida. We were given a newer Toyota Camry, as we requested a car of similar size to our car, which happens to be a 2001 Toyota Camry. My mind was just blown by this car. My husband veered off the road just slightly, and an alarm started going off in the car. I am in my 30s with 2 teenagers, so I thought nothing could surprise me. I was wrong. As soon as the alarm went off, I jumped in my seat in excitement and asked if it was what I thought it was. We have now been playing with this system to see how it works. I had to pick my jaw up off of my lap because HOW DOES IT KNOW??!!?? When there is a slight bend in he road, we don’t use a blinker, but we turn the wheel ever so slightly, and it doesn’t go off. However, if we’re in a straight lane and we turn the wheel so the car moves into the next lane a little or into the shoulder, we get the alarm. It doesn’t come on when we use the blinker, and I understand how that would work, but I can’t figure this out, and I don’t understand any materials I’ve found on it, so someone please, ELI5!

I think this site explains it really well, especially since there are a few different types of warnings/indications and systems: https://www.extremetech.com/extreme/165320-what-is-lane-departure-warning-and-how-does-it-work
But basically, there is a camera that is facing the road in front of the car. It is usually installed high up in the windshield. The camera detects any lane markings ahead and then can tell if the car is staying within those markings or if it is veering off course.
The technology relies on clearly marked roads so if you’re on a dirt road or on a highway where the lane markings have been faded or stripped down it might not work that well.
And there are different versions of the system – some of them resist you changing lanes without putting the turn signal on first, for instance, and others just give you a warning that you’re going out of the lane.
