Earlier quoted context omitted.
This is exactly what happened in Moscow after same tech was launched. It is much 'safer' on streets, since every entrance door and traffic intersection is equipped with cameras now. But I pick Portugal's approach every time — no public cameras, no dashcams, it is forbidden to record private persons in public without permission.
I’m in Portugal with kids right now and I can not think of a country where dashcams would be more useful. The standard of driving and adherence to the law of the roads is some of the worst I’ve encountered in Europe. I haven’t let go of my 9yo’s hand since we arrived in Porto a few days ago. Speeding is chronic and nobody gives a shit for the safety of you or your children here.
Talking about speeding, not sure. I am driving around Lisbon and speed limit is 50 in city, and lots of speed cameras. Though I am driving at 55 as limit and rarely see anyone going faster than that.
