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.

As a pedestrian I don't assume I can hear an engine. > (and a stationary car makes no tyre noise but combustion engine still makes some engine noise) 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.
