Most modern cars have it. We have speed limiters. As well as that, in the modern cars there is an indicator that notifies you when you are travelling at 50 km/h, 30 km/h, 80 km/h and 100 km/h. Maybe the first thing to do is to start with education on a voluntary basis. I use the speed limiter as much as I can because, clearly, I do not want to be found over the speed limit.
