Dude... Mathim. You are introducing a level of realism to the joke that doesn't fit it. They are shooting cannons from the back seats of their cars. The guy is transporting "sugar cane, tobacco and spices" in the back of his car... it's obviously a spoof, it's obviously a joke, and it's a cartoon. Lighten up, man. I hate to think of what you have to say to dead baby jokes.
If I could turn into a cartoon and swashbuckle all over the road pirate-style, I'd totally do it. Looks like fun! :)
