I got an EV so that means i am the smart

I wanted to be high IQ on this graph so I started walking everywhere. But I still have noisy exhaust.
Stop eating Chipotle

I’ve seen data from Austria indicating that 70% of vehicles exceeding legal noise levels are motorbikes, 20% are cars, 10% are trucks and busses. Vast majority of loud vehicles are modified in purpose to make more noise.
Also, where I live loud vehicles will not pass annual technical checks so people put in legal exhaust for the check and then put the illegal, loud one back in. This has nothing to do with people not having money to fix their cars/motorbikes and everything with low IQ street racing sub-culture.
Sound pollution is a legit thing.
I drive an EV, so I’m super smart! /s
There is a house in my neighborhood with your picturesque suburban short king that has a white Chevy Tahoe with the loud muffler setup! As annoying as it is on performance cars, I kinda get it. But in a family SUV? Dumbest thing I’ve ever seen. And he revs it in front of middle school kids waiting for the bus to boot. What a sad little man.
My car’s loud cause I’m poor and exhaust parts are expensive. It’s stinky inside sometimes too, probably not helping with the IQ thing. Guarantee it bothers me more than it does you
Modified exhausts are way louder than simply broken ones. Maybe 1% of loud cars I see are old and beaten up. In vast majority of cases someone paid extra to install custom exhaust.
I think you must live in a nicer area than I do lol. There’s like two guys with fart cannon Subarus, probably five with straight piped pickups, and uncountable beaters with soup cans/tin foil/hose clamps/rtv/bailing wire doing their best. We have cheap power and everyone wants electric but no one can afford it. There is exactly one Nissan Leaf owned by the school district superintendent. My car was $700 including all the parts to fix it. That’s pretty typical here. Cheapest exhaust I could fit was $800 alone when I looked into it, and almost certainly more now.
Probably difference between USA and Europe. In Europe beat up cars will not pass technical checks. To have a really loud car you have to replace the exhaust for the check and then install the custom one again. Only special kind of drivers have the time and will to do it. Mostly bikers.
That actually probably explains why bikers do it the most since there it seems like on most bikes the swap can be done in less than 30 minutes as the exhaust system is small and self-contained and easily accessible
Motorcyclists also believe a loud exhaust makes them more visible to drivers - to what degree this is true is debatable but sometimes the motivation is not pure malice like with cars.
I once paid over $400 to put a muffler onto a hatchback that a previous owner had deleted, I must be a fuckin genius.
You sure are.
I really like that my car is pretty damn quiet. Especially on start up and crawling speeds, so when parking for example. In every garage the car was in someone told me that they can remove a screw or something from the exhaust, so it’s always open and makes loud noises all the time. They all were pretty perplexed when i told them that i absolutely don’t want that.
If you want a loud exhaust just drill a few holes in it.
It’ll be loud af.
Sound is annoying but exhaust in general sucks. One thing that was amazing around april or may of 2020 was how clean the air smelt for a brief time.
2021 was a cyclist’s dream. Clean air and no cars
and everyone was instructed to give you at least 10 feet of distance :)
Australia, so 2m, but yeah
We were not allowed out except for a few exceptions, over of which was an hour a day of outdoor exercise
I would commute by bike to my preferred exercise location an hour away, ride for exercise for an hour, then commute by bike home again
I’d say it’s a curve.
This could be log scale. Or inverse log idk which way you want the curve to be
dB is already log scale
meanwhile IQ is not linear or log
True. It’s a Z-score measuring deviation from the mean. A step of one point somewhere on the scale just makes a statement about the relative rareity and not about a set amount of “intelligence” you have more or less than someone else.
