> Some cars and many motorcycles, depending on the road and driving style, will easily exceed the 95 and 80 decibel limits straight from the factory. Based on Car and Driver testing, examples include the 2016 Porsche 911 GT3 RS (108 decibels) and the 2019 Chevrolet Corvette ZR1 and 2019 McLaren 720S Spider, both at 99 decibels. Seems crazy to me that manufacturers are selling cars that are basically designed to be a nuisance.

  That's most likely the peak, so whenever the car is going full throttle.

With the exception (arguably) of the vette, those are uncommon high end sportscars. Much like with the speed limit, the owners are expected to be a little more cognizant of law abiding.

  Depending on where you go they can be very common. Drive around Beverly Hills or any of the nice parts of LA and you will see 911's and other high end cars more often than you would a Honda Civic.

  I expect them to treat fines like fees.

    Making fines matter to the people paying them is a separate problem. Finland scales then by your reported income for example.

Cars generally aren’t even that loud when compared to some Harley Davidsons. They’re literally continuous fireworks in the street and will trigger anti theft systems.

  People tend to modify their motorcycles to be louder. A legitimate reason to do this is for highway safety, but you can do that and be able to drive quiet where it will bother people... lots of people like the noise and drive obnoxiously because it's fun and don't care about the neighbors.

    It's not that they don't care about the neighbors... actively harming the neighbors is the entire reason it's fun. It's the school bully who grows up and can't keep punching people willy-nilly, but they can aggravate everyone in sight, and if someone says something to them they and their biker friends will beat them up. It's a way to feel powerful -- the ability to harm others with impunity -- and is observed in all kinds of people from bikers to gossips to dictators.

    > A legitimate reason to do this is for highway safety This seems like first-order thinking. Sure, it makes people more likely to notice the motorcycles. But it also makes people a lot more likely to hate motorcyclists and be unsympathetic to their plight when considering legislation, court cases, their own behavior on the road, etc. I bet loud pipes have done much more harm than good to motorcyclists as a whole.

      Cyclists in general get a bad rap. You can't tell me the baseball cards in my spokes are loud enough to warrant bottles being thrown, or remarks, but here we are.

This may be a "lying with statistics" deal, I'm sure many of those vehicles are that loud only when you really open the throttle which would be really reckless in neighborhoods and city streets where this kind of thing matters the most. The quoted cars are only possible to enjoy to their full potential on a track unless you're driving like an extreme asshole.

  I'm sure you can make a car that's quieter than these limits no matter how you drive them; they were designed to be loud because some people think it's cool. EDIT: Not sure why this is getting downvoted. Look at the ad copy of some of these cars. https://www.ford.com/cars/mustang/ https://www.ford.com/cars/mustang/ Literally the first line is "Hear the roar of a Mustang..."

    These cars being /performance/ oriented might be a hint. For a car to go fast it needs air, like a lot of air, air that engine needs to dispose of quickly in order to get a fresh batch, and adding complex muffler systems limits how much airflow you can have. Add to that ecological requirements and you have a very tight margin that car manufacturer can tweak in. Also just because car can sound loud when driven in full throttle, doesn't mean it has to. It is on the driver if he chooses to be a nuisance, not manufacturer(Straight piping an old beater car is dirt cheap, having a hole in exhaust is even 'cheaper' and is much louder than any of the expensive, performance oriented cars in question.

      Turbo makes a car faster and increases air intake -- yet make an engine quieter, not louder https://www.torque.com.sg/features/turbocharged-cars-why-quieter-than-non-turbo/ https://www.torque.com.sg/features/turbocharged-cars-why-qui...

>Seems crazy to me that manufacturers are selling cars that are basically designed to be a nuisance. This is a really odd take. The noise in that case is a by-product of how the car's powertrain is designed.
- TulliusCicero 4y ago
  That doesn't really conflict with what GP said.
- dsizzle 4y ago
  You're saying the mufflers are optimized to be as quiet as possible for the given powertrain? Anyway, why the focus on the "powertrain"? I can understand wanting to accelerate quickly. Are you saying there's a relationship between acceleration and noise level? Clearly that's not true for electric cars, but is it even true for ICE cars? Turbo increases acceleration and yet lowers sound levels.

To be fair, if people drive them responsibly then they shouldn't be hitting that level on a 25-35 mph street. Or really anywhere other than an on ramp or highway passing, etc. Also, I'm curious about the testing specs. I assume it has to be a specific pressure adjusted for things like altitude, temperature, and other environmental features. How do the cameras handle those variances so not to ticket someone with a legal car that goes over the limit due to an environmental factor?

  > To be fair, if people drive them responsibly then they shouldn't be hitting that level on a 25-35 mph street. Or really anywhere other than an on ramp or highway passing, etc. You can easily go full throttle in 1st or 2nd gear and make a ton of noise under 30MPH.
  - giantg2 4y ago
    "You can easily go full throttle in 1st or 2nd gear" And doing so would not be considered driving "responsibly". Hence my use of the word. You can also drive irresponsibly and make a ton of noise in other cars by doing things like dumping the clutch.

The question is, why is the federal government allowing these vehicles to be sold / why are states allowing them to be registered? If they don't meet federal standards, they're not legal to operate on US roads. They weren't even legal to import, which means they should be confiscated and destroyed. Customs was fond of doing this for illegally imported Skylines and Land Rovers...why not brand new Porsches?
