Why is it best to keep a space cushion around your vehicle?

Maintaining a space cushion around your vehicle is a critical safety practice that provides you with the necessary time to react to unexpected situations. When there is adequate distance between your vehicle and those around you, it reduces the risk of collisions, as you have more time to respond to sudden changes, such as another driver suddenly braking or an obstacle appearing in your path. This buffer can also be crucial in adverse weather conditions where stopping distances are longer.

The other options do not directly contribute to the essential function of a space cushion. For example, while preventing other drivers from cutting you off can be a secondary benefit, it doesn't address the primary purpose of reaction time in critical situations. Similarly, making your car appear bigger or attempting to drive faster does not align with safe driving practices. The focus should always be on safety and the ability to manage unforeseen circumstances efficiently.
