This is true in a scientific, not practical sense, in any American city.
Engine noise always dominates, because 1% of cars are simply purposefully obnoxiously loud, and you need to be powerful and well connected to get enforcement of existing laws about vehicle noise in your neighborhood.
Yeah I don't mind the traffic noise outside of our house - it's mostly road surface noise which is dampened to white noise, and most petrol engines aren't that loud at those speeds. But it's the occasional sports car or moped that is the most annoying. Those are getting replaced by electric models too, but I wish they did something about the noise decades ago.
For me, while I find the 1% of purposefully obnoxious engines to be annoying, the thing that grates on my nerves is anything more constant. So for me, road noise dominates in what gets under my skin, not engine noise.
I cannot speak for you or anyone else, except to say that you have no right to speak for anyone else, either, who has not granted such right to you.
