You will not guess what car gadget I found

I possess a driving licence for a long time. I love driving and I have always thought that I know it all about new trends when it comes to cars. A few years ago I have heard something about a reverse camera. Sadly, I wasn’t really interested in that subject at that time. This is 1 of those moments when you look back and you entirely don’t understand yourself – how could I hear about these cameras and ignore this?
