My 1 year old son has just started making noises when he plays with cars. He doesn’t say “brrrrm” or similar, he says “eeeee”. We own electric cars.

Think of it, a future where cars, buses, trucks, tractors go “eeeee” instead of “brrrrrm” in the minds of children.

@CatherineFlick
It's not the big city which is noisy. It are the cars within on fossile fuel that are making most of the noise.
@englram, it's the cars within that are making most of the noise. All cars are noisy and produce pollution, regardless of traction. Most noise over a certain speed (40+ IIRC) comes from the tyres.
