The point about the noise brought up by Erdrick: I second his thougts and would add that the problem of noise is relative. Now the petrol engines are overhelming the noise produced by an EV. In a future where EV will be the normality the "average noise" on the street will be much lower so you will notice when an EV is approaching also from the little (compared to today's standard) noise it will produce.
And after all... what they put in a horn for? (Yes, I'm Italian!
