In a new patent application, Google is looking to make its self-driving cars a little safer for pedestrians … by covering the cars in glue.

With safety being a top concern for Google’s self-driving car program, the company has been looking for ways to reduce the risks for both riders and pedestrians, and its new patent application shows just how far Google is willing to go in its search for novel solutions to old problems.

Pedestrians involved in car accidents are hit with two impacts. The first is when the car strikes them, and the second is when they hit the ground. The idea behind Google’s new patent is to prevent or at least lessen the secondary impact by making pedestrians stick to the hood of the car rather than being thrown onto the road or into another object. This could also help prevent pedestrians from being hit by other cars.

One potential problem for Google’s new idea would be how paramedics are supposed to remove injured pedestrians from the hood of the car, especially considering the fact that they are supposed to be sticky enough to hold onto a person during a collision.

There is also the fact that covering your car in human-sized flypaper means you would also be picking up all kinds of dirt, trash, and bugs, but Google offered a solution to that problem by covering the adhesive layer in a thin shell that would break open on impact, ensuring that the car stays clean and the pedestrian stays…sticky.

The idea may seem ridiculous, but then again, so do instantly-inflating balloons that prevent you from colliding with your steering wheel.
