Aston Martin Will Build You Your Very Own Supervillain LairSony Crammed a 9-Inch Touchscreen Into a Single-DIN Car Stereo Stay on target Distracted driving is a huge problem. Some have called on Apple and Google to implement features that automatically lock down phones when they detect that you’re driving. Nissan would like to offer a more old-school solution: the Faraday cage.You know, the shield made of conductive metal mesh invented by Michael Faraday in the 1830s. To keep drivers’ attention on the road, Nissan has embedded one in the center armrest of a Juke (much like the one pictured above, minus the Nismo upgrades). They call it “Signal Shield,” and it repels cellular, WiFi, and Bluetooth.Nissan says that Signal Shield is about “creating a ‘phone-free’ space and time,” adding that it allows for “a digital detox and a drive that’s free of incoming distractions.” It’s a lot like enabling airplane mode, except you activate it by shutting your phone in a box instead of tapping a button on your screen.Blocking Bluetooth signals does, of course, mean that your multi-hundred-dollar smartphone can’t wirelessly pipe any tunes you have stored on it through the Juke’s stereo. No worries: Nissan has included a good ol’ fashioned USB port so that you can make a (gasp) physical connection.Signal Shield isn’t for everyone. Some of us aren’t fazed by the ever-blinking LED or the odd buzz or chirp from a new notification. That’s fine, Nissan says. Signal Shield is about giving drivers the option, especially “those [drivers] who struggle to ignore the beeps and pings.”There might be an opportunity to profit here, too. Maybe you can corner the market on digital detox Uber rides by requiring your passengers to pop their phones inside when they get in. The whole Faraday cage thing has already proven successful in more than a few bars, after all.
