Completely baseless assumption, but I think it’s just a continuation of the phenomenon when toddlers get hyped for trucks/tractors/combine harvesters/anything that is big and loud, maybe because it’s associated with power, I don’t know. Some people just stay at this toddler’s mentality and they see everything that’s big and/or loud as something you can boast about. See also: loud exhausts, 6400 deciBel motorcycle sounds, etc.
