There's an awful lot to like about what's going on here. They've managed a nice trifecta of bonkers: racing school buses is already nuts, making them go on a figure 8 track that produces more T-bones than a Waffle House adds to the crazy, and then one bus is shooting fireworks, finishing the job.
I'm glad to see crazy stuff like this still goes on. I bet as driving gets progressively safer and safer, we may see crazy-release valves like this becoming more popular. Then I can finally start my motorboat-with-wheels conversion destruction derby races.
