I almost was a victim of highway robbery

This happened yesterday. Some 10km after crossing the French-Spain border. A car approached the side of my car and a guy starts yelling and gesturing through an open window as if there's something wrong with my car. Like a punctured tire or a door is open. We're going 120km/h so I can't hear him. I start slowing down and I see him pull up to a small service area of the highway and start waving with that green high vis vest. I approach his car by the side and try getting information through a slightly open window, but he backs up constantly gesturing me in a frantic fashion. Luckily, there were signs on the highway in English warning about highway robberies and not to talk to strangers. So, I decided to just drive away.

I just wanted to let people know that these are real. In the moment I was acting like I would normally in traffic and thinking of helping people or seeing if I'm in trouble. Not thinking someone might rob me. It was pure luck of having a tire pressure sensor in car and knowing my tires are good and the warning sign on the highway that alerted me to other possibilities.

Found a video on the internet that looked exactly what was about to happen to us, so stay safe and don't trust strangers.
