Reminds me of the cars that have artificial exhaust sound enhancement piped inside!Morons with their stupid bass speakers in their cars. I do however enjoy watching them around town, middle of winter when it is below freezing and middle of summer when it is well over ninety and they have to have their windows rolled down so everyone can hear their sweet "system" even though the rest of us have our windows up and heat/ac turned on and cannot hear them anyway.
I have often wondered how many times in the history of mankind has a person gotten lucky from someone hearing their sweet system bumping? The correct answer should be zero.
