    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

      There’s quite a large discrepancy between this image and OPs image. This image says the survival rate of 30 mph (48 kph) is 60%, while OP’s image says 50 kph it’s at 20%. I wish they included a source for the data that could explain it.

      This is the same issue I take with braking distance scales. They often vary wildly, and some don’t even follow a quadratic increase in distance like you’d expect.

      The energy difference is only really relevant if the thing you’re hitting is significantly heavier or at least similarly heavy like a house or another car. For a person it’s still much worse, but that is moreso because of the high hood of the car.

      I know pickup trucks are heavy, but I’m surprised they are 16 times heavier than a Honda civic. The more you learn.

        We wouldn’t have so much trouble with this if all men had the same size dick upbringing that leads to the sort of maturity that leads people to be not shit.

      I got hit by a large SUV doing between 30mph and 40mph a few years ago. I can’t tell you why or how, but I had a split second to twist and plant my hands on the hood and jump so I went up instead of under. Went into the windshield (broke it) and then got launched when she slammed on the brakes. It put my radius and ulna into my hands, my back into my guts, and knocked my brain so hard I gave the emergency crew a phone number that belonged to a girlfriend I’d broken up with almost 20yrs prior. Took me a year to be able to write again, not just physically. I’d start putting words to paper and end up with gibberish because between my brain and my hand it didn’t connect. Had to leave post-it notes around the house as a check list- did you eat, bathe, brush your teeth, feed the dogs, piss? My ability to sleep was wrecked, no circadian rythym. I don’t entirely believe in fate, but how the fuck that didn’t kill or cripple me boggles my mind (what’s left of it) daily.

    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.

      I live near an intersection. Drivers will ten second horn blast because someone won’t crawl up the arse of the car in front of them just so horatio can mount the kerb and get into a sliplane they can’t exit until the lights change anyway

      So what i’m saying is you’re underselling the stupidity

      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.

        I’m guilty of this when using a web browser, I’ll scroll down a page and open relevant posts into new tabs until I’ve accrued several. Sometimes I don’t get to them for quite a while so if I upvote it’s surprising how high the number jumps until I realize it’s sat there for half a day.

        I try to refresh when commenting because 9/10 times someone else has already commented the same thing since the internet is dead but sometimes I forget.

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

    There’s a new neighbor at the end of our street with small children. She always puts one of those green children at play signs in her front yard, yet insists on driving 25-30mph down our suburban street. The rest of the neighbors hate her.

    I remember a public safety ad being shown that showed the difference in either 30 and 35mph or 30 and 40mph. Was quite dramatic.

        There are also far fewer of them per passenger, so fewer chances for one to come by. They are also operated by professionals who can call in sick if their ability to operate the vehicle is impaired.

        A bus could be ten times deadlier in a crash than a car and it would still be safer if it carries fifteen passengers. It could be a thousand times deadlier if operated by a drunk person and still be safer than cars because drunk people don’t operate the vehicle when getting home by bus.

        Roads. Cars and busses will be on roads.

        Tracks. Trains and light rail will be on tracks.

        I’d say both are pretty predictable.

          Consider what happens when a train passes through a place where pedestrians cross vs. what happens when cars do the same.

          How often do trains pass through places they’re not allowed to at times they’re not allowed to? How often do cars? (Red lights, stop signs, yield signs…)

          How often do trains veer off course of the line they’re moving in (aka. change lanes)? How often do cars do it?

          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
