Building anything requires trigonometry, unless you just say "fuck it" and hope the thing doesn't fall apart, which is a pretty stupid way to live life.
Literally nobody is "remaining alive" because their shitty bike is louder. If anything, they're increasing the odds of someone hitting them out of rage. Also, notice I've said "moral", not "ethical". They're not the same thing.
Since it's impossible to determine whether any given answer is true or not, the logical course of action is to only ask question with observably objective answers. Examples:
What are the next lottery numbers?
Will it rain tomorrow?
Where was the exact location of Troy during the Greek war?
