Oh they'll get you speeding on photo radar alright. The question is if the fine will actually get to you before 3 months because the system is so poor. And then you ask for the photo evidence and they'll tell you that you have to pay for it (this happened to me once).

Fines for running red lights are an instant very serious offense and two of these will suspend your license. Speeding depends on how much you went over the limit but it's a bit more flexible.

4-way stop signs are the stupidest idea when there is very little traffic or when there is a lot of traffic in a given intersection. In fact, they only work well in a moderately trafficked intersection; vehicles are supposed to stop once and then go through the light.

Roundabouts solve this entirely because for low, medium and even high congestion areas they are very effective at clearing out traffic. Sure they are definitely harder to tackle but as long as you're not in Braga (go around the outside or you'll crash into someone) you will have little to no issue doing them as most people are civil enough to tackle them properly. The issue is placing them because they require significantly more space and not all locations are suited to having them; if you notice most new planned roads all include roundabouts.
