I think a lot of people might be confused by the term "car activists" because the car, as well as the attitude permitting its dominance, is so pervasive in the status quo, and passive/active support for the status quo doesn't register as activism in everyone's mind.
So to be clear: The U.S. is a country where, in many many places, the "car activists" won and successfully channeled untold billions and billions of dollars into imposing their ideology. The U.S. has built incredible amounts of roads, highways, parking lots, and interchanges exclusively for cars, which it has done at great expense by taking on debt and bulldozing existing neighborhoods. It has lax police enforcement and penalties for injuries and fatalities caused by motorists. It has tons of laws requiring businesses and housing to make accommodations for cars. And society passively tolerates the environmental, noise, and visual pollution cars cause, as well as the congestion they create and the people that they kill.
