The reason I asked why electric included was because brakes within electric cars can operate very differently than that of combustion cars. Whereby the brake pads within electric vehicle almost do not need replacing for the life of the car.

Vastly reducing the amount of brake dust that is given off the vehicle in comparison to combustion vehicles. The same way in which riding a bicycle produced brake dust but not in the same volumes are combustion cars.

Car tires I completely agree however almost anything that rolls uses rubber and as such if we introduced more bicycles instead of cars we would also be polluting the streets with rubber. You could argue however that this is offset by the health benefits this would provide people rather than being sedentary in a car.

With regards to communities I would argue that nothing is stopping people from walking around and meeting their neighbours. However, people can visit other communities or extend their community boundary using cars and railways etc. Therefore our sense of community isn't just those immediately, but those across town as well.
