Glad to see this here. In many jurisdictions, if the law doesn’t say it previous rulings do: you must invoke the rights to silence and to counsel.
It sucks but plenty of judges want to give the police every chance they can get, like those dickheads who OK’d forcing people to unlock their phones because “you already gave police your fingerprint”.
There is so much theft of cars happening because car manufacturers did fucking nothing to improve security. Now a guy with a laptop, and antenna, and radio software can clone your car keys and all they have to do is hang around enough to capture a few of the rolling code changes. They can do it from outside your house and through some obstructions too.
So yeah a Faraday cage of some sort for your car keys is just a good idea now. Guess that makes us all criminals.
