Car noise is generally from tyre, not the engine. Generally. If you ever have a chance to stand beside a highway where car usually zoom by at 100kmph++, you will hear mostly the tyre sound and rarely the sound of engine nor the exhaust. ICE car these day are so well-tuned to make less noise from the engine and exhaust, but they can’t control what tyre the owner put on.
The only thing electric car solved is eliminating tailpipe pollution, the rest is still there. There’s also danger on how quiet the car are in low speed, so whirling sound might needed to prevent pedestrians harm. It’s better than nothing though, but it’s still way worst than public transport or bicycle.
