  • Thank you. I was mostly worried about running 5 screens at all times. Every mirror replacement system I’ve seen in pictures uses really bright screens and the E has 3 infotainment screens on top of that.

    So if we count them as 5W each (12.3 main displays are probably hungrier, but camera displays are way smaller, and they’re almost certainly IPS), that’s ~25W, so 150 meters by your calculation? Doesn’t sound that bad tbh. And on top of that the 12.3" ones can be turned off.







  • Anyone with a spectrum analyzer can see people using their earbuds, they can’t deduce any useful information from that. Several analyzers? Yea, can triangulate signals, so what. They still can’t know for sure who they belong to, since BT doesn’t transmit identifying info unless you’re pairing (aka discoverable), and even then it can be randomized.

    Also I posted in in a different comment but I’ll leave this here too.

    I can get a lot further from my phone than I’d be from the drink machine in who knows how many fast food spots before service drops.

    A typical fast food restaurant has dozens, if not hundreds of wifi and bt devices. Nothing surprising when your phone has to fight to get loud enough for your buds.

    From a quick search, bluetooth classic has 79 channels, and if there’s 2.4Ghz Wifi in use, it has 14 in damn near the same frequency range.

    If you’re worried about tracking - there are far easier ways to do that than hope your BT devices are discoverable and then try and match the (possibly randomized) device IDs to you.


  • Depends on the device, there was a story recently of a Nissan infotainment system that was perma-pairing as long as you had the options screen open afaik. If your earbuds are pairing close by, as is the machine - you can probably make some rudimentary motion tracking. Gonna be inaccurate as hell though, and it relies on both devices permanently being in pairing mode.

    This part though is way easier to explain with interference. A typical fast food restaurant has dozens, if not hundreds of wifi and bt devices. Nothing surprising when your phone has to fight to get loud enough for your buds.
