Google has patented a new adhesive layer which is placed at the front of their self-driving cars, in the case of a collision with pedestrians.This new technology isn't to annoy pedestrians and take them on unwanted joyrides whilst stuck to the front of the vehicle but it's actually placed to save lives.
The 'sticky' layer is if or when a pedestrian is struck by the front end of the vehicle it can help reduce the damage caused by the vehicle. It will help prevent the pedestrian bouncing off the vehicle hitting the ground or other cars and will stop whiplash-like injuries.
The patent is described to work on contact the self-driving car will then react (hopefully) to the incident and press the brakes easing the car to a standstill with the civilian stuck to the front of the vehicle.
Google has patented the sticky front system but it does not mean it will be implemented. It is also noted that the sticky front technology can be used on regular vehicles as the patent only covers self-driving vehicles.
It is noted that the primary use for the sticky front of the vehicle is there to prevent secondary injuries but what if a pedestrian is run over and part of their body is stuck to the front, will they just be dragged? I'm assuming the vehicle will slow down but it does show that sticky front won't prevent all types of accidents.
