Personally, I'm keen to see if the proverbial doors get blown off the first few gens of electric cars, and the FOSS community makes headway.
I would happily buy an old Leaf if I knew we could handle all the software ourselves, and just do battery swaps when the range wasn't enough any more.

That would not surprise me at all.
In the UK, they have a huge tax incentive as company cars. People are definitely getting them for the tax benefig, and not giving a shit about the electrics.

Though honestly, if it means almost all company cars are at least regenerative braking, and the tech is there is someone does want to use it, it's not the worst thing.
I might end up with a PHEV in a few years, as most of my driving is very short distance, and I can't justify the cost of a 200mi+ BEV for the 1 trip a month that needs it. And putting second hand PHEVs on the market helps that.

These are different attack vectors.
The classic one was listening to a key, then impersonating it later.
Rolling keys fixed that.

For keyless, the usual attack is working as a relay.
Victim is 30m from their car, too far for keyless.
Attacker stands between the car and the victim with a transceiver that links the car and the key together, despite the distance, and opens it.

And whenever you're trading options for shits and giggles, remember that the market can stay irrational far longer than we can remain solvent.

This is why I believe in some geo-located communities.
It's easier to find common ground when you're complaining about the same weather.
And then when you're interacting with the wider communities, your host community can give context to your way of thinking.

Turns out Poole was a decade ahead of AI, with the self-destructing threads.

It's traditional to split Fellowship at Rivendell.

Don't give them ideas!

WMK values are generally quoted as transmission for 1m thick for insulating materials. (watts lost per meter squared per delta kelvin).

For example, PIR board is about 0.022. So for 100mm thick, it would be 0.22W lost per degree difference.
The aerogel glass is quoted at 0.053
Mineral wool is 0.038
Brick is 0.600 on a good day.
Pure aerogel is about 0.018.
Glass is about 1.000 (varies).

I can see this being used in situations where light is needed, but a window is not.
I can definitely see the benefits of making utility walls out of it.
It's going to be expensive though, at least until aerogel prices come down.
And it's not going to beat using the same depth of PIR board, or mineral wool. (assuming the numbers are all correct)

This is my eventual goal. I want the house to be automated to the point that the only interaction I have, is just living.

If I walk into a room, the system takes into account the time of day, day of week, outside light level, and brings the lights up.

If it's really cold outside, it raises the radiator flow temperature. If only I'm at home, and it's a monday morning, it only raises the temperature in the bathroom, kitchen, and my office. That kinda stuff.

I always find it a bit amusing when I see "shut down due to radar activity" in my 5GHz logs.
