C. The space between your vehicle and the vehicles in front, behind and on either side of you.
The space above the dura mater is called the subdural space. It contains a small amount of fluid that acts as a cushion for the brain. Bleeding or fluid accumulation in this space can lead to subdural hematomas or hygromas.
The subarachnoid space is a space filled with cerebrospinal fluid located between the arachnoid mater and pia mater membranes that surround the brain and spinal cord. It serves as a protective cushion and helps with the circulation of cerebrospinal fluid.
The ventral subarachnoid space is a region within the spinal cord where cerebrospinal fluid circulates. It is located between the arachnoid mater and pia mater layers surrounding the spinal cord. This space helps cushion and protect the spinal cord.
The subdural space contains a thin layer of fluid known as the subdural fluid, which helps cushion and protect the brain from sudden movements or impacts. This space is located between the dura mater (outermost layer of the meninges) and the arachnoid mater (middle layer of the meninges) surrounding the brain.
The cerebrospinal fluid resides in the subarachnoid space that surrounds the brain and spinal cord. It acts as a cushion to protect these structures from trauma, provides nutrients, and removes waste products from the central nervous system.

A "space cushion"
There really is no advantage to increasing your space cushion, the problem is that other drivers always think you are being courteous enough to allow them into your lane.
In California, it's a "three second cushion" of space when following other vehicles. http://www.dmv.ca.gov/pubs/dl603/teen_htm/drivingskills.htm

"Space and visibility" refers to defensive driving techniques that result in space for the vehicle and visibility for the driver.
A space cushion is the area of space around your vehicle that provides a buffer between you and other vehicles or obstacles. It allows for safe maneuvering, reaction time, and stopping distance in case of sudden changes in traffic conditions. Maintaining a proper space cushion helps reduce the risk of collisions and enhances overall road safety. By keeping a safe distance, drivers can respond more effectively to potential hazards.
if another driver makes a mistake... etc
gives you the most visibility and the greatest space cushion.
An anchor space is any of eight spaces lying along the cushion during a game of billiards, in which any balls in this space are treated as being in balk.
