Should you try to keep a "space cushion" around your vehicle whenever possible? a. yes, when another driver makes a mistake, you will have time to react b. no, space cushions are unnecessary. they take up valuable space on the freeway c. no, someone may try to crowd in front of you d. yes, but only on city streets

A. Yes, when another driver makes a mistake, you will have time to react

Explanation:

Yes it is good to make space cushion between two cars because due to some urgency when front vehicle applied brakes then the driver of the rear car will definitely take some time to react.

This reaction time may be between 0.5 s to 0.8 s for different people

so the rear car will move with same speed for above reaction time and it will cover the cushion distance between two cars

If we will not maintain this cushion distance between two cars then we can see that the two cars will collide and that may cause many accidents

so it is correct statement and correct option would be

A. Yes, when another driver makes a mistake, you will have time to react
