I figured out exactly what the lines on my car's backup camera mean

I loved the first two cars I ever owned, which were a 1997 Honda Civic and a 2008 Mazda 3. I racked up tens of thousands of miles on them, and I look back on them with many fond memories. However, when I eventually purchased my 2021 Hyundai Elantra, it was the first time I experienced many modern-day car features, such as a backup camera (also known as a reverse camera).
