  • Dutchman here. I love riding in fresh snow. Very serene, empty roads, and plenty of grip. It takes effort, and I’ll be wearing lots of layers, so I’m very warm.

    Fuck old snow or black ice though. Like you say, snow is rare so I don’t have studded tires or chains and stuff. Usually the cycle tracks are well salted and plowed though. There’s even an app mhat can de bicycle route planning over plowed roads only.






  • Why wouldn’t we accept that? We accept so many deaths by human car drivers.

    It won’t be hard to have self-driving cars be 10 times safer, which will save many lives. But that does mean we have to accept some deaths by self-driving cars.

    No deaths would be awesome, but for that we would have to completely restructure all existing traffic infrastructure. In the current case there will allways be scenarios where even the best drivers (human or robot) won’t be able to avoid a collision.






  • A lot. Most of the strength from a beam comes from the top and bottom, because these are the parts that have to stretch or compress most when the beam is bending. The middle part is contributing relatively little for strength.

    That is why metal poles are often hollow, that saves a lot of material and weight without losing much strength.



  • It makes a lot of sense. I make eye contact with drivers, because then I’m mostly sure they’ve seen me.

    With a driverless car I’d like to know it has acknowledged me, so I can start crossing the road. Otherwise I’ll wait until it has completely stopped. So there needs to be some sort of feedback that’s intuitive. Might as well be eyes.



  • That’s true in theory, but if you talk about megameters to a European you’ll get very weird looks.

    An engineer will understand what you mean, but still laugh at you.

    But it’s a non-issue for anything on earth, where you’ll have 40.000 kilometers at most. Not a lot of time is spent talking about x thousand kilometer.

    Any notion that a kilometer is “too small” is laughable.
