It's a jungle out there and now road safety campaigners are lobbying for cars to be made to look more like animals because, they claim, it could cut road accident rates.
An experiment to show that people have stone age brains that are unconsciously attuned to detecting the movement of animals, rather than inanimate objects such as cars, because the former played such a key part in the survival of our ancestors.
The American study shows that the modern human brain carries the visual priorities of our hunter-gatherer ancestors and is still more likely to track a tiger - or even a chipmunk - than cars and lorries.
The researchers are saying that cars don't need to be redesigned - just painted in animal designs and point to the 'flying tiger' airplanes from WWII as an example of a vehicle that's difficult not to notice.
