What's worse? Speeding on the road or polluting the air? This fancy new camera developed by researchers from Spain's Universidad Carlos III de Madrid doesn't care about speed. It cares about how much you're polluting the air from your vehicle. It'll let authorities pinpoint the vehicles that are the worst offenders.

Five percent of vehicles on the road account for 90 percent of toxic emissions. So instead of forcing every driver to take an emissions test, the camera is meant to measure pollution coming from a vehicle on the road in real time.

Using a modified multispectral imager that uses a series of filters to snap images across varying bands of light, it reveals distinct signatures of various types of toxic gases.

It's a great idea to be honest. Lets hope we see more of this on the road. [Universidad Carlos III de Madrid via Gizmag]
