This is the key to safe(r) driving. Most people only consider time in the sense of how long it will take them to get from one place to another. However, with driving, one needs to consider time on multiple levels. It takes time to accelerate, and it takes time to stop. It takes time for the surface of the tires to produce enough friction with the surface on the road to make a curve or a turn. Most importantly, it takes time for drivers to notice an upcoming issue, recognize its level of threat, formulate a plan, and execute that plan.
It's here that I note that time is something that people can give themselves. Most importantly, they can give themselves time by leaving early. However, drivers need to also recognize that time is a part of an equation that includes distance and speed. If speed is a constant, drivers can give themselves more time to react and time to stop by increasing the distance between themselves and the nearest danger--which is usually the vehicle in front of them. Similarly, drivers can give themselves more reaction time by slowing down their overall speed.
Now, many people are too impatient for those two simple adjustments, which is rather ironic. Most people do not drive far enough to make a speed difference of say 65mph over 55mph get them anywhere sooner than leaving 5 minutes earlier would have achieved (note: one has to drive over 30 miles at 65mph rather than 55mph to save 5 minutes). Thus, people are not only reducing their ability to react and respond to unique situations, they are not really saving the time that they think that they are. As far as distance is concerned, riding someone's bumper might allow a driver to vent their frustrations, but it tends to actually slow traffic down while making the situation more dangerous. In fact, in busy traffic, a tailgater can bring a highway almost to a stop farther back due to their use of brake lights.
Time alone will not solve all of the issues while driving. There are some circumstances which no one can prepare for, let alone control. However, it is the best way to give a driver the fighting chance needed to make it through an unexpected or difficult situation.
