In Australia, having a drink in your local pub is a pastime that many like to enjoy. Although the government makes it clear that drivers should not consume more than 0.05 BAC, it is difficult for drivers to judge just how much they have consumed while in a pub. In addition to this, many factors will influence how much a person can consume before hitting the drink driving limit. These factors include weight, gender, and how much food has been eaten -- as food consumption affects the speed at which alcohol enters into the blood stream.
In lieu of how hard it is to safely determine how many units of alcohol can be consumed before driving, there is a strong case for having wall mounted breathalysers in each pub. Breathalysers measure how many micrograms of alcohol there are per millilitre of breath and then warn users if they have gone above the legal BAC limit in Australia. When a drinker blows into a wall mounted breathalyser, the ethanol present in their breath moves through several chemical stages before being measured by a microprocessor that gives an indication of blood alcohol level (BAC).
After giving an indication of a person's BAC and whether it is too high for them to drive safely, that individual will be less likely to drive. As it is difficult to judge how much alcohol will affect each drinker based on their individual physical factors, a wall mounted breathalyser in the pub will allow them to make an informed decision when it comes to getting home. Over all, 30 percent of fatal crashes in Australia occur as a result of drink driving, and each year over 19,000 people are charged with a drink driving offence. Alcohol can reduce coordination, slow reactions, and induce a poor perception of speed and distance. Although many people may feel as though they have not consumed enough to become a dangerous driver, it is too often the case that they are just above the legal limit. Being caught driving while above the legal limit has serious repercussions. Penalties include: fines of up to $5000, jail sentences, and demerit points as high as 5, or a driving license disqualification.

If you've ever tried to imagine the Lord of the Rings, Dark Lord Sauron when he represented himself in the Second Age, as the All-seeing Eye, peering into the dark, you might just be ready for the Mobileye.
