Doctors have noted another big factor in the prevention of head injury and brain injury including concussions: motor vehicle design. When the vehicle is less likely to crash and crashes are made more survivable, lives will be saved. Motor vehicles are now specifically made to both be easier to drive and more durable so the passengers have less chance of injury. Most car manufacturers test their vehicles thoroughly, and safety standards are now government policy in many developed countries.
Better engine performance, better lights, better steering, and other aspects of better car design have become more prominent over the last few decades. While it is sometimes difficult to determine that good car design prevents crashes, it can be proven that poor car design is dangerous. Ralph Nader’s famous work, ‘Unsafe At Any Speed’ has been cited by many as the work that impelled car designers to take a closer look at their manufacturing policies and the public at large to consider car safety an important factor in their automobiles. Trained observers in Brooklyn and Long Island have also seen that the occupants of larger vehicles tend to be more safe than the occupants of smaller vehicles.
Cars can be designed to be safer and reduce head injury, by absorbing the impact when it comes to a crash, that would otherwise harm the occupants. Things like crumple zones protect from frontal crashes, but side impacts are more difficult to plan for. Most modern car designs have removed any interior protrusions, so penetrating injuries are now much less common in car accidents than they once were
