Auto supplier Siemens VDO has developed a new ghost driver (person driving in the wrong direction) monitoring system that’s able to read passing road signs in order to warn drivers they’re heading into oncoming traffic.

The system works with Siemens’s current road sign recognition technology and utilizes a camera positioned on the back of the rear-view mirror to detect 'Exit Only' signs located near highway access points. It also works in conjunction with sat-nav systems to give drivers advanced warnings of changing street types and the direction of traffic flow.

The device sounds like another useless invention that’s supposed to make driving safer but usually makes drivers less aware of what’s going on around them. If you can’t figure out for yourself that you’re headed in the wrong direction, perhaps it’s best that you don't drive altogether.
