Loud cars and motorcycles seem to be everywhere.
One guy doing it might not be that meaningful but, that’s true of just about everything.
I'll say this. In numerous cases, loud motorcyclists do it for their SAFETY. Most motorists don't pay attention to a small vehicle, especially if it were quiet. Most motorists are listening to music or something else, so the road doesn't have their utmost attention. The LOUDness of their motorcycle jolts the unattended motorists that a tiny vehicle is nearby.
As for the excessively loud, etc, that's above my understanding.
Finally, your biggest defense against loud motorists (in your home) is double drywalled and good insulation in your home. It will become a lot quieter and you'll have energy efficiencies by doing so.
You might never have 'bought' the argument but direction of the pipe doesn't take away from the fact that MOST people DO hear them as they begin to pass you. Except when they zip through going illegal mph. That's something that...baffles me. Why zip through WITH loud mufflers. They don't seem to be too bright but...fate comes for those cyclists fairly quickly.
If you want to become an organ donor, then go ahead. But you can't make everyone else deal with the externalities of your choice.
Loud pipes do help. Your minimizing of it doesn't negate that truth.
As for self-driving etc, ummm that's a bit off tangent. This is a discussion about noise pollution with an emphasis on motorcycle and the rationale to it.
I love it when someone who deliberately has a loud motorbike insists it has to be loud for safety reasons. I have met a few people who have claimed this. It always appears to be the only thing they do for safety reasons, the rest of their lives being a messy blur of insanely risky life decisions.
They don't wear chaps. Nor helmets. Nor anything else for safety. But let's reduce the argument only to your perception of this issue. /s Come on. Let's be more rational than this.
Yes, motorcyclists are risky. Yes they do numerous risky things. But everything we (a more general claim) do is on a gradient. It's on a sliding scale. Let's stop reducing this issue to 'loud noises don't help much. Nor has anyone, that I met claimed this. They are reckless people'.
