What you mean is "it's really not bad for me".

Noise pollution is horrible. It is jarring and causes stress (health issues), and poor sleep (health issues).

This isn't just a vague immaterial thing, this is a genuine negative impact on people's health and by extension life expectation. If people could "just ignore it", obviously they would, right? Some of us can't. Luckily I moved away from most noise and live in a quiet area now, but nothing is stopping some arsehole with a modified exhaust driving down my road every night. It could start happening at any point. At which point, I'd want laws to stop it happening.
