At city speeds, tire noise exceeds engine noise in many internal-combustion vehicles as well.


At highway speeds it definitely does, but not necessarily at city speeds as the speed is low (and a stationary car makes no tyre noise but combustion engine still makes some engine noise).

This of course also depends on the road surface and tyres. Where I live we have rough asphalt (with large granite chips sticking out) and rought tyres, at least in the winter. The highway noise is practically all from tyres.

No, but often enough for it to be a factor. As a pedestrian I don't assume I can hear an engine.

Unless you have a start-and-stop, and it's approaching insanity to require that stopped petrol cars have speakers that make engine noise if they turn off the engine.
