Really? You're going to double-down after I've made it clear that you look like an idiot? Whatever. It's not your reputation could get any worse.
Let's see if I can explain this in a way even you can understand:
Attempt #1: You need to be able see outside of the car to drive, which is why cars have windows. A Faraday cage would obstruct the windows in an unsafe way. (You generally want holes no bigger than about 1/10th of the wavelength.)
In my first post, I said that a wrap wouldn't work. This is why. Only a drooling moron would think that my "right idea" comment meant we put the car in a larger cage!
Attempt #2: You don't need a Faraday cage that covers the whole car. You only need one around the part that is transmitting. This isn't always easy. (To disable On-Star, for example, it is recommended that you completely disconnect the module.) The only way to be sure that your shielding is adequate is to use a tool like a spectrum analyzer. Such a thing is well-beyond your ability, of course, but trivial for anyone of ordinary intelligence.
I'd add a third thing, but you're not worth the effort I've put in already.
