You good to drive? Unfortunately the answer to that question isn’t always the right one, and if a cop has to answer it for you it’s a good bet they’ll be getting the truth. One of the reasons is that they can actually see how much you’ve had to drink by measuring it in your breath. Of course nobody should hop in a car after drinking any amount, but with the BACtrack Vio Smartphone Breathalyzer, you can take the role of cop before one rolls up on you or your friends if there’s any question. It’s a disaster averting tool that you can get for just $39.99 at Cult of Mac Deals.

LAS VEGAS — Keith Nothacker is living proof that persistence pays off.

Cult_of_Mac_CES_2015 Nothacker is here at the giant International CES gadget show to introduce a key-size version of his pocket breathalyzer — the first personal, police-grade breathalyzer approved by the Food and Drug Administration. Connected by bluetooth to your iPhone, a quick puff into the $49 BACtrack Vio will tell you instantly if you’re too juiced to drive — or take part in any other activity best done sober.

But 13 years ago, Nothacker was fighting the FDA to bring the device to market.
