    Oh neat, I’m one of the green people in the first two rows. Not 100% sure how fast they were going, somewhere in that range. Just glad it was a short sedan and not a big truck/SUV. I live in the US, could’ve easily been a truck and ran over me instead of me toppling onto the hood.

    But just wait for the deafening screaming of people when 30km/h limits are enacted in front of schools because that would dramatically reduce lethality of accidents, while costing car drivers maybe a few seconds of drive time, if at all. It is quite a spectacle.

      How dare they put an authoritarian surveillance system (speed camera) near the school. This is an unfair tax on normal people. Its not about safety, it is about control. - most of my city until the province outlawed speed cameras entirely.

        In all seriousness, paint doesn’t enforce speed. What you need is to rebuild streets for that speed. Have a look at the Netherlands for reference. You need pretty little enforcement when streets are built for 30 km/h. Narrow, priority pumps at crossings for pedestrians, where your car seat is punch through your pelvis if you go anything faster than 30 km/h …)

          You are right, but there were also several studies done that proved the speed cameras lowered speeda significantly, even after the camera had been relocated.

          Lets not let perfect be the enemy of good. Those cameras reduced speeds and generated revenue for the city that was specifically dedicated to making streets safer, including bollards, lane narrowing and speed humps. The removal of the cameras both made the streets more dangerous, and cut funding for real safety improvements. All because speeders were getting caught speeding and considered that unfair.

            Sure. But if roads are built for the speed, the road enforces the speed. If driving faster will shake you so badly that it feels like an accident, most people won’t do it. Also making streets narrow, with tight road crossings and curves, and subjectively more dangerous to the car drivers, actually makes streets safer, especially for people outside of cars.

            Of course that is not possible everywhere and then speeding controls, including cameras are the next best thing.

              We can’t just update the roads for free. The cameras were a big part of the plan to make the roads safer.

                Sure and don’t get me wrong, this pro reckless driving action is nothing I support either.

    Great now do SUVs for the Americans. Go ahead and assume they are not simultaneously being shot at just for the purpose of keeping the simulation simple.

    This needs to be updated.

    Getting hit by a pickup truck at 30 MPH is similar to getting hit by a Honda Civic at 120 MPH for kinetic energy.

    That’s besides the fact that pickups have a much taller hood vs sedans so there are significantly higher rates of head/internal injury.

    Taller cars and trucks are more dangerous for pedestrians, according to crash data

      Your math is wrong. Kinetic energy scales linearly with mass, quadratically with speed. The graphic you included supports the idea that at same speed, the pickup truck has double the KE. The 120 mph sedan has dramatically more KE than a 30 mph pickup.

      Assuming that your sedan has exactly half the mass of the pickup, it would match a 30 mph pickup’s KE at 30*sqrt(2) mph, which is somewhere between 40 and 45 mph.

        Roads. Cars and busses will be on roads.

        Tracks. Trains and light rail will be on tracks.

        I’d say both are pretty predictable.

          I have definitely heard of children being killed by a car while waiting for a bus in a bus shelter several metres away from the road

          I have read about cars smashing through walls of houses

          I have read about a car used to kill the children of the driver in a lake well away from the road

          Cars are not guaranteed to be on roads when they are killing people

        The op image uses speeds much slower than that. The top speed in op is 60km/h which is about 35mph
