Recently, Google’s driverless car company Waymo has obtained a new patent to reduce the impact on the object by changing the hardness of the body surface in the event of a collision. Imagine that if an unmanned vehicle hits a person, it can change its hardness and become soft. There is no doubt that this can greatly reduce the damage caused to the human body.

Usually, the impact is the main cause of casualties in a car accident. Therefore, the principle of the patent is to sense the surrounding objects in time and determine how to change the hardness of the car through one or more sensors, and then reduce the stiffness of the car by changing the tightness and relative displacement of the cables, support bars and spring clips at the bottom of the car body. To reduce the damage caused to the human body.

Although the patent sounds good, neither Google nor Waymo currently said that they will immediately deploy the patent in their unmanned vehicles. And the downside is that how to protect the personal safety of the people in the car is still a tricky issue.
