Tire noise increases with speed and weight. At freeway speeds, tires make 60% of the noise of a typical ICE vehicle[0]. Electric cars are also heavier than ICE vehicle due to the battery. High speed AV only roads would probably have more cars on them too, so even more noise.

- xnx 1y agoYes. In my personal road situation I'd be happy to exchange more tire noise (which is more of a consistent white noise) for the abrupt and annoying other car sounds. There's still a chance that net tire noise would be same or less: "Tires running higher inflation pressures generate lower noise levels compared to those with lower inflation levels." https://www.tirereview.com/the-fight-against-tire-noise/ https://www.tirereview.com/the-fight-against-tire-noise/ I suspect that other design choices (e.g. fender skirts like on the Honda Insight) could be made that would further reduce tire noise.
