One of my favorite recent movies to come out is 22 Jump Street. A very memorable point in the movie was when Channing Tatum and Jonah Hill crash the football helmet go-kart into the goal post of the football field at the end of the game after a tense and “expensive” chase around campus. The resulting shot was this.
The shot shows bystanders on the field and the previous shots give a strong sense of realism and make it look like the whole endeavor was very dangerous overall.
How I would have done the shot is film the leadup of the chase to where i was eventually using a long telephoto to close the depth of the car to the goalpost at the last second to give the sense of a real crash while the car is either in reverse away from the post, or very slow and sped up for that split second hitting the post, added the explosions in afterwards through some VFX work, which due to the masking of the shot and the colors and such, that is what it looks like was done here. toppling the goalpost would be done very controlled with a crane for safety, attached to the top of the post and lowered slowly, yet out of frame and the tighter shot seen here would be easily possible with bystanders at a safe distance. Everyone would be safe, and no real fire or damage to vehicles or people would happen.
