This sounds so bizarrely immature to me - like the trolls that sabotage their vehicle's noise suppression. I wonder if they realise they catch people's attention because the onlookers are simply waiting for them to leave so they can resume hearing themselves think.

Also, I thought EVs make noise to alert pedestrians and bicyclists, because the general public isn't used to quiet cars yet and honking the horn is likely to have the wrong effect.
