You just contradicted yourself. You claimed that adding more lanes slows traffic.

Adding more lanes obviously increases demand, which is the point. You want to get more mobility from Point A to Point B. Induced demand doesn't mean that adding lanes will slow traffic; it means it will increase capacity and that capacity will be used.
