But people still blindly trust carmakers to make reliable and difficult to hack fully software-based and with always-on internet access self-driving vehicles.

They can't even secure the thing that directly unlocks your car and enables thieves to steal it.

Two factor authentication for cars, here we come! Though, searching for this phenomenon shows articles at least 3 years old warning to get Faraday cages or otherwise wrap fobs in aluminum foil.

But do they really transmit all the time, or do they contain accelerometers or something to prevent battery from being wasted?

Why is it transmitting without the user pressing a button? Is that a feature? As you walk up to the car it automatically starts like magic? I'm not familiar with these newer cars.

Nothing new, has been going on for a while now. Market is already providing your own "cage of Faraday[0]" for your fob. [0] https://www.amazon.com/faraday-cage-key-fob/s?page=1&rh=i%3A...

Yeah this has been a thing for years in the UK. Myself and my wife put our keys into a metal lunch box in the hallway which mitigates this problem, which was prompted by both next door neighbours getting their cars broken into.
