  • But they’re made of the same material so it shouldn’t make a difference

    They are not designed to protect you against the same amount of force as a motorcycle helmet. That study just proves that expired bicycle helmets are still good for bicycle accidents, not motorcycle accidents. I rest my case.

    The point in the video that you are missing is that the material when new, has oils that makes it spongy and more effective. Those oils evaporate with time. The demonstration with the hammer is just to show very casually how brittle the material becomes compared with a new one, and the difference is evident.

    The study you linked, as yourself said, is for bicycle helmets. They are not designed to protect you against the same amount of force as a motorcycle helmet.

  • Magic Earth is closed source but it claims it respects the users privacy, it uses open street maps and it has decent traffic data for navigation for some countries. It also has the advantage that you can configure it to stick to the original route if you prefer. This is very important for me because sometimes I want to take a scenic route, or just routes I prefer but that are not necessarily the fastest.
