"Tailgating" has existed for a long time. In recent years, the appearance of "tailgating"has changed considerably with drive recorders and SNSs.

However, today I won't talk about that.

I rarely run on the “passing lane” on the highway.

Basically, I keep running at the minimum speed (80km) and drive slowly in the "driving lane".

This is because there are so many benefits in this way.

(1)Not tired

High-speed driving demands processing power that overloads the brain, and the consumption of physical strength due to body tension is intense.

As you can see from the calculation, it is clear that the fatigue of high-speed driving is converted to the time taken for a break in the service area.

For example, let me think the 300km long expressway (Kawasaki-Toyota), which is the return route to my parents' home.

When running at an average speed of 80km and 110km, there will be a difference of less than 1 hour in arrival time.

I drive on the highway for 5 hours (without traffic jam).

Since I take about 4 breaks, each break takes about 18 minutes.

Let's assume that 110km travel is 1.38 times (= 110/80) tired than 80km travel.

In this case, assuming that the break time is proportional to fatigue, the break time for each break is 25 minutes, and the total break is about 100 minutes.

In this case, the advantage of arrival time is only about 30 minutes.

However, I think that fatigue is "linear" with respect to "speed" is a fairly optimistic assumption.

Considering that visual information is two-dimensional, visual and tension fatigue is proportional to the square.

That is 1.38 ^ 2 = 1.90.

If calculated with this value, the total time required for the break is 137 minutes, and on the contrary, it will be delayed by about 7 minutes.

In conclusion, I think

"Fast driving" that accumulates fatigue is ridiculous"
