Is it possible to build a true Faraday cage into a car? One that blocks WiFi and cell signals.
Guessing the glass might be the biggest problem...

Some upmarket cars have twin pane glass, some sort of layer in-between the panes would block signals. Always used to have telecom problems unless using external antenna.

Great, the driver doesn't get distracted but would suck to be a passenger in a Nissan on a long journey if you were incommunicado for the duration...

They are just doing an isolated central box. I want to do the whole car.

So you can’t stream music to your car from your phone.

One step forward, two steps back.

Also as above, so passenger can’t use their phone or the drivers phone.

Pointless, why would you buy car that limits you like that?

Yes it's possible.

But not desirable.

Cars will become increasingly connected in the years to come.

Not 100% without some serious costs and modification I reckon.

I have a particular car in mind, where reducing the possibility of hacking would be a very good thing. Just imagine a light weight and cheaper version of 'The Beast' (the Presidents Limo) where WiFi and phone signal can be controlled.
A mobile office of sorts...

Some Ford's have heated windscreens where the filiment could act like a Faraday cage for the glass.
Tbh instead of sheilding the car it would be a lot lighter and cheaper just to get a multifrequency jammer, cost less than £50 from China and will block gsm, 3/4g WiFi and gps.

You will run the remote risk that ofcom could slap you with a large fine but they didn't take action against anyone when fm ipod transmitters were all the rage, had one in my car back in the day that when powered up defaulted to the fm frequency 100.00 which was the same as kiss fm, very chikdish but funny in trafiic interupting those who were listening to kiss fm as that was the loudest played fm channel back in the day.

I thought most cars were a natural Faraday Cage anyway.

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...

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.
