    I lived near a highway and it was so weird when you started hearing it randomly and it wouldn’t go away for 10 minutes. Cars going fast are actually insanely loud.

      I recently learned that it’s not the engines or whatever that’s loud. It’s the sound of the tires on the pavement that makes the most of the noise (save for some douche that intentionally made their mufflers loud, obvs)

        Yes, that’s why the virtual engine noise generator of EVs only runs until 30kph/20mph before turning off. At that speed the tyres are already loud enough to be audible to pedestrians
