Theoretically all those interactions breach the social contract and could be acted upon by making complaints. However, someone loudly driving a multi-ton car down your road is always "okay".

Also... I live in a low-density urban neighborhood currently and it's the loudest place I've ever lived. Mostly it's road noise, but also one of my neighbors parties 12+ hours every weekend playing music very loudly. Some people are just loud, but cars make everybody loud.

Cars with fart pipes installed are the same kind of violation. Modern cars with functioning mufflers or electric powertrains... aren't actually that loud.

Until their tires hit asphalt. Cars have to go very slowly for the engine to be louder than the tires, and that noise is a function of weight, and electric cars are heavier than equivalent ICE cars.

Most of the sound from a modern car with a functioning muffler is wind noise. You can barely hear the tires unless you're standing right next to it.

"Electric cars are heavier" is some silly nonsense where people went looking for something to complain about. You can make an electric car as light as you want, with the trade off that it implies making the battery smaller and reducing range. But the Model 3 has a ~300 mile range and weighs the same as the average car.

What? Like wind hitting the extremely aerodynamic surface of the car designed specifically not to catch the wind? I have never heard or read this in my life - it is widely known that tires-on-pavement is the biggest contributor of car noise. That roar you hear standing a quarter mile from a busy highway is not wind, it's the tires.

Again, this contradicts everything I've read and/or is just willfully ignorant. You can't make EVs superlight by stripping down the body, for example. The battery is the heavy part and while they may get more mass-efficient over time EVs are now and for the foreseeable future strictly heavier than same-size ICE cars.

EVs aren't the savior of the environment, public transit is. EVs are better than ICE cars in most ways, but for noise all cars are a problem and EVs are worse.

Like the sound of a hundred cubic feet of metal displacing the air at 40 MPH and leaving vacuum in its wake, yeah. That they're designed to be aerodynamic is the reason they're not that loud.

Now you're talking about highways. People don't typically drive at highway speeds on city streets.

People have agendas. They need some reason for electric cars to be bad.

The Model 3 weighs around 4000 pounds, as do the Ford Taurus, Chevy Camaro and BMW 3 series, all vehicles of approximately the same size.

Some cars are lighter than this. Some are heavier. In general the existing production electric cars tend to be on the heavier side because premium car buyers prefer longer range to less weight, and that's the trade off. But there is nothing inherently requiring that, and in fact electric cars with smaller/lighter batteries would be cheaper, so that's likely to be what happens as more affordable electric cars become available.

> You can't make EVs superlight by stripping down the body, for example.

If you have an electric car with a 1500 pound battery and a 300 mile range, there is a fairly obvious way to make one that has a 100 mile range and weighs 1000 pounds less, and it doesn't require changing the size of the cabin. You might even get more than 100 miles of range by doing this, because now the car weighs 1000 pounds less and requires less energy to accelerate.

> EVs aren't the savior of the environment, public transit is.

Public transit is inapplicable to any place without enough density to support it. More than two thirds of Americans live in suburban or rural areas. We could build millions of new high density housing units and the majority would still live in suburban and rural areas -- and that's unlikely to change, because housing is scarce and only a fraction of those units would be converted specifically because of how many more units you can put on a lot for high density housing. If you build 20 units to a lot you could double the number of urban housing units while only reducing the number of suburban/rural units by 2.5%.

All of the people who live there will continue to need cars.

> Now you're talking about highways. People don't typically drive at highway speeds on city streets.

That was an illustrative example. Tires typically overtakes engine noise at about 25mph. That's city street speeds. (In most car-dependent cities 40-50 is also typical city street speed.) Again, this is why tires are the majority of car noise. When you hear a car pass by on a non-highway road, you're mostly hearing tires.

If wind is a serious factor either you need to publish your secret findings or link me to some research I'm not finding.
