Question

In a sport called Rallying, there is a driver and a co-driver. The co-driver says things (or rather gives directions) to the driver. I know what they are sayong, but does anyone else have any idea what is being said here? (PS: If you have no idea, don't be shy! You can say it is complete gibberish if you like!):

"Crest over jump! Jump into 3 left. Straight 100! 50 right care rocks at side! Crest into jump, into jump, into 2 crest 3 right into long 4 right tightens! Straight 50 2 right......finish!"

Answer 1

sorry no idea.

Answer 2

Not positive on the crest term(I'd recognize what it was when I play a rally cross game but yeah not sure, think it is basically like a hill) but the number is meant to say the type of turn. They grade from 1-5. 1 is a turn you basically just go toward the inside and don't really have to turn, up to 5 a really sharp turn. The 50 and 100 are length in yards. Care rocks at side should be self-explanatory.  

Answer 3

"Crest over jump! Jump into 3 left. Straight 100! 50 right care rocks at side! Crest into jump, into jump, into 2 crest 3 right into long 4 right tightens! Straight 50 2 right......finish!"
