You are not wrong. The have already found ways to hack into newer cars because the infotainment system (radio and display) is so integrated into the car. With DBW, electronic assist steering and ABS controls they may not be able to take complete control of the car, they can definitely impair how you can drive.I completely agree with everything you just said, my point is I don't trust wireless communication devices because they are suseptible to undesired operation and even worse the right person with the right knowledge and the right tech tools can take them over, I have seen remote control cars and other wireless remote control stuff operate on their own without my permission, I've seen remote control cars drive off on their own, and to top it off they are now making full-size remote control cars, they even have a racing league for them, I saw a headline last year where a full-size remote control battery powered indy car turned left on its own and crashed for no reason and they didn't know why, most important thing to understand about all this is that ANYTHING remote control can be controlled by more than one remote, you are not the only one with a remote to your device, go ahead and buy into these new "cars" if you want to and yes those fcc rules are definitely for INSURANCE PURPOSES, think about it, SMH
My other reasons for not wanting a newer car has to do with the fact that they are making so many things one year or partial year only in order to have the latest and greatest to offer new buyers.
I still say no one is going to try and rebuild a 2019 car/truck in 2040. I bet they will still rebuild a 2000's model in 2040, and we know they will still rebuild stuff from the 60's and later.
