    No, no updates needed unless I encounter a bug or they add a new feature I really want.

    Fine, but maybe the update fix a bug that hit other users and that still not have hit you, be it for sheer luck or any other reason.



  • That’s exactly what I wanted to say: 30 is one of the most common speeds in the EU. They are not new and have been around since the 70s/80s.

    As far as I know, the city speed limit is 50 km/h for a very long time. In the 199x, when I got my driver license it was it, the push for the 30 km/h limit is a relatively new thing, maybe last 5 years. Not to say that before there where not some 30 km/h zones in cities, but the default in every urban center (small or big) is/was 50.

    Cities are pushing for 30 as a default speed.

    Now yes, but is a relatively recent thing, and only for big cities.

    You have thousands and thousands of kilometres of residential streets with T30. If you do not optimize for that as a manufacturer, you shouldn’t build cars.

    Italy currently has an estimated total 2700 km of 30 km/h residential streets. My city alone (Milan) has about 58.0000 km of streets (only residential streets, the total is way higher).
    Maybe manufacturer are not that dumb if they do not optimize the engine for the equivalent of the (less then) 5% of the streets of just one city in a state.

    And I suppose that other states are in a somewhat similar situation.



  • If your car uses more fuel for slower speeds and for such a common speed as 30, the manufacturer is an idiot.

    Or the manufacturer just optimized the engine and the gearbox to be more efficent at a certain speed.

    In the end the consumption is tied to the rpm of the engine, if you need to stay on high rpm to go to 30 km/h on a lower gear because the gear ratios are optimized thinking to a certain set of speeds (50, 70, 90 and 130 km/h which are the most common in EU), you will end with a higher consumption.



  • I would be terrified of using a bluetooth mesh network in a situation where private, encrypted communications are illegal. That would be literally walking around transmitting your intent. It’s a great idea in a free country though.

    You have a point but that would means that the only other solution is to fall back to personal comunications, every electronic channel is unusable in such situation.

    In a dystopia, you want to blend in.

    Or you can simply have so much irrelevant data that the few important bits are lost in a sea of randomness if you don’t know where to look.

    Something like deltachat has the right idea there - you have to look like boring email on the network. Maybe even layer on stenography -sending boring emails with cat pictures, but your messages are hidden inside them.

    The main point of using bluetooth is to not rely on a centralized server that can be compromised and/or shut down.
    If you still use email as transportation layer you could just write an app that really has e2ee, plausible deniability or any other feature you want since in the end you are relying on the same centralized infrastructure.

    Honestly, I would probably go with sneakernet. A microsd card can be hidden very easily, are difficult to detect electronically, transport virtually unlimited text, and be encrypted in-case the mule gets caught to prevent networks being exposed. The latency is just a necessary evil.

    The latency is not the problem, it is already known that to move large quantities of data the fastest method is to send an hard drive (or whatever else).
    The real problem here is where the mule can go.
