You were obviously claiming to know a great deal about cars electronics systems, yet all you have managed to prove is - you know nothing much at all.

He’s proved his lack of knowledge on many occasions in the past.

Yep!

It is better to remain silent at the risk of being thought a fool, than to talk and remove all doubt of it. DNJ seems to completely ignore this.

I made no such claim. I know next to nothing about electronics and don't really want to know because I simply have no more space in my head for them. But I do know about device functions, i.e. what stuff are capable of or could be made capable of. Hence, I am able to tell you: if car manufacturers want to, they can lock things down. Since the referenced video was talking about locking things down, it's reasonable for me to believe the lock was in place. The current economics of the world also tell me the same: people, manufacturers are getting desperate. When desperate, they lock things down.
