Reducing the size and weight of a car goes a long way for environmental impact. People seem to think it's just less fuel being burned.
In reality, there is a reduction of almost every consumable. Smaller tyres. Less tyre wear. Less brake dust. Less oil used. Less chemicals when washing. Less wear on the road surface. Less manufacturing emissions. Less disposal when it's done.
The relationship isn't linear either. Doubling the weight of the car results in about 10x the surface wear.
