Sorry if this has been asked before but how do you get Excellent on destroying the car? I think there was a way to do it but I’ve forgotten.
Use Chun 
Before the car bounces, do equal damage on the left and right sides. You need to cause a certain amount of destruction on both sides, but you need to do it before the first burst the car makes.
It’s not based on how fast you do it, so just using Chun doesn’t get you excellent.
I learn something new every day. thnx
