Pilotage is to tell the driver the way ahead according to the road book prepared in advance. It is a concise expression, which is agreed in advance, because many times time does not allow you to speak slowly. If I remember correctly, I usually use the expression "left four, 80". It not only indicates the direction of the curve, but also indicates the bending degree and reference speed of the curve.

The so-called "learning from foreigners to control foreigners", when you find that your opponent is piloting in a simpler way, will you still use the phrase "turn left, bend four, speed 80"? "Left four, 80" is a very scientific expression. Whether you can chat or not depends on your own judgment. For example, if you find a long straight line on the road, the pilot thinks there is no problem. Of course, you can say, "well, yes, we are driving very fast ahead, and we should win the championship in the stage." Don't push too hard behind, for fear of an accident "and" It seems to rain soon ". Of course it is appropriate.
