That is because many cities/politicians refuse to enforce reasonable noise limits on automobiles. It should have never been legal/normalized to have exhausts loud enough to need hearing protection while outside of the vehicle.
those ppl will create noise at whatever cost lmao, I bet they’ll start attaching external speakers at some point to compensate for the lack of engine noise
I see this argument a lot about EV’s being heavier. And while it is true (for now) the actual weight difference is fairly nominal when comparing two popular closely spec vehicles.
Curb Weight
Toyota Camry
3310 lb.
Tesla Model 3
3582 lb.
+272 lb.
The report goes on to note that pm10 is still reduced in heavier EVs with a smaller tradeoff for increased pm2.5. There are nuances sure, but I still interpret this as a net positive on particulate matter and a step in the right direction. That is something we should not discourage in a world that is still struggling to stop pumping carbon into the atmosphere. Fuck cars, but let’s try to make incremental improvements where we can.
Abstract:
Assuming lightweight EVs (i.e. with battery packs enabling a driving range of about 100 miles), the report finds that EVs emit an estimated 11-13% less non-exhaust PM2.5 and 18-19% less PM10 than ICEVs. Assuming that EV models are heavier (with battery packs enabling a driving range of 300 miles or higher), however, the report finds that they reduce PM10 by only 4-7% and increase PM2.5 by 3-8% relative to conventional vehicles.
Since much of the noise pollution from cars comes from tire noise, I doubt EVs will reduce noise pollution that signifcantly.
It’s not tire noise I’m hearing in bed at 1am while some yahoo is treating residential roads like a racetrack.

That shit ain’t legal, it’s just not enforced.
Legal where I live, and in many states too.

Near motorways where they go high speed the reduction will be negligible, but is material around lower speed streets.
Something not mentioned is the significantly reduced brake dust as most EV braking is regenerative.

Noise pollution is a function of speed.
At low speeds, it’s mostly engine noise. At highway speeds, it’s mostly tire noise.
Many city streets have near highway speed limits or designs that easily allow cars to reach near highway speeds.
