Anthony that causes the car to behave in a way the driver isn't expecting (collision avoidance) would probably lead to less safety rather than more. Besides, even Tesla autopilot can be fooled and certainly isn't designed for cars driving inches apart. The air bags have been covered in other comments but similarly would probably reduce safety, not increase it. The cars are very much designed for safety, and to absorb impacts, which is why they are so much heavier than previous generations.
