NDrive GPS With Built In Breathalyzer
GPS systems are great. You start your car, plug in your destination, and the device tells you the shortest and fastest way to get from point A to point B. Here is a GPS with a little added feature. It will tell you if you have had too much to drink to drive safely. I am not sure how accurate this could be; everyone’s body chemistry handles alcohol differently. And different states have different “legal” limits when it comes to alcohol in the blood. But it is a good idea, I guess. “When you first start the application it calibrates; accounting for the already present amount in the environment and the sensor, and then it asks you to blow.”
