Hi readers!

It's such a real long time from my last activity here. Like on the previous post, I mainly write (or just repost some motorsport contents) in Racevoltius Facebook Fanpage. Since now I got more free time, I plan to write more about my thoughts on motorsport world, both in Indonesia or overseas.

And also, recently I am quite active in GT Sport's Sport Mode. It's quite fun, due to the fact that you will be matched with opponents that have same driving level with you. Should you be interested to driving simulator that's not "really Real", Gran Turismo Sport worths to try!

Before the start of Monaco Grand Prix (or while you are watching Nurburgring 24 or preaparing some snacks for Indy 500), let me ask you a question. Are you familiar with "slipstream" term?

Slipstreaming, or some people say drafting, is a method used by racers to align their vehicle behind the opponent. When a car runs, there is a drag that is created from airflow. The faster it runs, the more drag will hit the car, causing some effects, like shaking vehicle or speed reduction. To memorize this thing, let's use "dirty air" terms.



Behind the dragged car, there is a space which has less drag effect compared to the front part. Let's use "clean air" to label this space. There are so many advantages for the rear racer to be in this clean air, such as:

-  Decreasing drag, which will increase speed to overtake opponents
- Saving fuels

In stock car racing, slipstreaming is much more advantageous, not only for one driver. Clean air sector has slingshot effect which might attract rear drivers. Thus, despite of oval track, drivers still have chance to gain higher position if they can take advantage of this effect. Well, actually I still need to study the effect on stock car racing, due to the racing nature which differs from normal on-road racing.

Here it is my short glossary about slipstream. On the next glossary, I might continue my writing about racing flag rules.

Unlike many other sports which basically have same basic rules for different championships, motorsport is an entirely different world. Each racing championship might have some slightly different rules, despite the fact that they might run in the very same circuit (for example F1 and GP2 championship, which both run on Catalunia Circuit). This time, I would like to share flag rules, which is one of the basic rules for many kinds of on-road racing championship.

This time, I will focus on the flag rules that shows the current condition of the track. Check it out the graphic's below!

Hope that simple explanation helps you in understanding flag rules. Next I will focus on the instruction flag rules. See you on the next part!
