I could be wrong, but I think there are other possible reasons SUVs were mentioned. I think having more walkable cities would part of (or at least adjacent to) the degrowth movement. As such, SUVs are kinda the poster child for the vehicle size arms race which makes roads less safe for pedestrians and cyclists.

I wouldn’t be surprised to see pickup trucks on that list too, however they do have a somewhat more plausible use case.
