In cases like these it's the context that matters: where i live most people are employed in the construction industry, so every day you hear big IVECO trucks at 6am shaking the ground; but no one is mad at them because it's just some poor soul trying to get to work, and trust me, you can't make trucks of that size loaded to the limit with cement pallets quiet. On the other hand when you get that one idiot with no muffler and 5 speakers in each door, you can't not hate them, since they are doing it SPECIFICALLY to piss off everyone in a 100m radius
