I equate this with those that drive around with their bass boxes booming away to announce their arrval, not necessary and nobody cares. It is the conclusion that I've come to watching people with these noise makers, it's all about NOTICE ME, HERE I AM, HERE I AM,  just silly nonsense. Why not take the money wasted on these things and invest it in making your vehicle more functional. It also reminds me of these clowns driving around with those wings on the back of their ricer, never gonna get it going fast enough for it to do what it was designed to do, it's big it's loud and it makes you notice me.... "hey look at everyone looking at me I must be a celebrity", no not really it just makes you look the fool.
