The easiest way to judge a safe gap is to use the two-second rule.

In wet weather or on poor road surfaces you should double this gap.
Similarly, should you speed to maintain a safe two second gap? Judging distance and speed can deteriorate with age and older people may take longer to react. So always keep a safe distance from the car in front.
