Sneaking into the HOV lane or using a dummy will soon be detectable thanks to researchers at Loughborough University. The new camera not only records cars traveling in HOV and other lanes, but it can also count how many real bodies are in the car by sensing water and blood.

The initial use of the technology is to monitor the HOV lanes and prevent hoodlums from illegally driving in the lanes, but government officials are interested in the technology to monitor overall traffic and highways during peak times like rush hour. I guess the solution would be to fill that inflatable doll with pig's blood to fool the cameras into thinking you are really traveling with another person, but if you're that desperate you should really just look into leaving a bit earlier.
