Google has patented a new sticky technology to protect pedestrians if – or when – they get struck by the company s self-driving cars.

The patent, which was granted on 17 May, is for a sticky adhesive layer on the front end of a vehicle, which would aim to reduce the damage caused when a pedestrian hit by a car is flung into other vehicles or scenery.

This instantaneous or nearly-instantaneous action may help to constrain the movement of the pedestrian, who may be carried on the front end of the vehicle until the driver of the vehicle or the vehicle itself in the case of an autonomous vehicle reacts to the incident and applies the brakes.

Car companies have already taken steps to protect pedestrians from impact.

However, the patent observes, existing technology found in production vehicles does little to mitigate the secondary impact a pedestrian may experience .
