Well this sounds like it could get a bit messy.
In a bid to make their self-driving cars less of a menace to fleshy pedestrians, Google appears to be experimenting with the idea of covering the bonnet of their vehicles in an adhesive, flypaper-like 'eggshell'.
Stick with us here.
Google has some sound logic behind its unusual new patent: If you're unfortunate enough to be struck by a car, it's not usually the first impact that does the damage, but the secondary impact - either onto the car's windscreen, roof, another car or the ground. It's this nasty second phase that sees your body fly with huge momentum into an unmoving solid surface, breaking all sorts of important soft bits.
