That's a really rude and dismissive take - the impact of cars has been immense, in particular the ways in which they've been given primacy as a mode of transport and the ways in which that necessity has interacted with our laws and infrastructure development (sabotoging of public rail transport, parking regulations and the creation of car-dependent suburbia, pedestrian safety, highway projects decimating communities of color, etc. etc. etc.).

To blithely state that nobody could make such a claim seriously is an attitude which actually has a really fitting term: carbrained.
