Faraday cage in car?

That's assuming you're in a car with people you might actually want to talk to. If I was being driven across town by some random racist minicab driver who only wanted to talk about racism and football, I would make sure to be glued to my device.
Who mentioned minicab drivers?Eric Mc said:
I thought most cars were a natural Faraday Cage anyway.
They are. However the effectiveness decreases with frequency related to the size of the holes. Smaller holes, more effective to a higher frequency. There's an equation for that.On the windows question:
At it's simplest it could be a grid of very fine wires which you could see past.
I think there are also transparent electrically conductive films that can also be used.
Then you've got all the wires which go through the body. Every one of those would have to be decoupled.

People managed long journeys before mobile phones were invented. It's a little known fact that humans can also communicate by something called 'talking'.
But if you want to travel in car from which mobile phone signals can't escape, how about - leave your phone at home? Now there's a staggering thought...

Some things just makes life easier, why limit yourself now.
I’m hazarding you’re alluding to drivers on their phones which isn’t always the case. I was actually hit by a driver on their phone texting last August but I still see the use for phones more than just talking devices in cars.
As a military EMC engineer who has worked in automotive EMC too...
I'm going to say it's going to be bloody difficult. But how difficult depends on what frequency you want it to work over? And how much attenuation do you want? Do you want it to stop "stuff" getting out or "stuff" getting in. E-field or H-field you worried about, or both?
