Your definition of “scam” is not what other human being use. Causes unnecessary back and forth.

Green hydrogen is water electrolysis with solar power, not scam, it works, it is just a question of making it economically viable. Hyperloop is just stupid, but within the realm of possible. Cold fusion is the only scam here.

Cold fusion is a scam, not a bad idea. There is no scientific basis for that. Is as bad as “infinite energy engine”.

Ok, I am the hacker from France that compromise the golf in Florida. Now what? Do I start the engine to pre-condition the car from across the ocean? You know you cannot even drive with the app, just start the engine… There is no reason at all for going all the way and doing this. None.

So you have hackers mass compromising rooted android os around the world hoping for an overlap with Volkswagen users with the app, so that they can hack the app to unlock a car hopefully located near them instead of just opening the first car you find with a suction cup on the glass.

Ok, got it

So? What is the problem? It is not unsafe to start a car. Could you blame VW if the car started because of unsafe software on your phone? Is there really a risk of malicious actors targeting car apps to start random cars?

Why does my car needs to verify the integrity of my phone OS? Why does my car cares? It is not like my car is using my phone to make money transfer between banks or managing third party medical information no? Why do you need a safe OS to start the AC on my car?
