Google has a solution to help mitigate injuries in the event a pedestrian and a self-driving car collide: human flypaper.

In a patent issued this week, the search giant describes a “system for protecting a colliding object from a secondary impact, after an initial impact with a vehicle.”

The patent calls for a giant sticker to be placed on the front end of a vehicle, with a special coating over the layer that is only broken when something collides with the vehicle, exposing the adhesive and helping the colliding object to remain on the vehicle.
