It would be a waste to give them separate antenna, they both operate on the same frequency (and often with the same radio, although the BT side of an m.2 card is often supported by usb instead of pcie)
I would disagree with the suggestion that there is no correlation between battery energy density how violently they burn. There is a direct connection between the state of charge and how aggressive the failure is for lithium batteries in cases where they are punctured, cut, or folded. (Not uncommon in car crashes)
I am not saying this as a dig on EVs, ICE vehicles can go die in a hole for all I care, its just a reality that more energy is more energy and you can’t escape it.
All domains you purchase through cloudflare have a fancy button on the gui to add dmarc and dkim that just say “reject” so people can’t pretend to email from your domain, pretty neat feature imo. (Not actually useful if you are trying to use it as a custom email domain though, lol)
No one with a grain silo would deliberately contaminate it with matter that would rot.
