We always notice that maximum number of road accidents occur when the driver is drunk. Take the case lady Diana, if her driver was not drunk, she would be amongst us today. So everybody who drives and drink beware, secret camera are there in your car to monitor you. Japanese carmaker Nissan has unveiled new technology designed to detect whether a driver has been drinking. The cars consists of odour sensors that that monitor breath, detectors which analyze perspiration of the palms, and a camera that checks alertness by eye scan. To top it all, if the system thinks that the driver has drunk too much, the car will not start. Nissan says that the sensitivity of the technology still needed to be worked out. If a person has one beer, it's going to register, so they need to study what's the appropriate level for the system to activate.

Nissan, Japan's third-largest carmaker, says the technology is still being developed, but it will eventually be introduced to reduce road deaths.
