I think you've misinterpreted something. No one is suggesting banning trucks or lorries; only SUVs. They are not the same. Trucks, lorries, vans, buses, coaches, all provide meaningful utility. SUVs do not.
They do to many people, but not to most. Where do you draw the line?
I personally like the "Hochdachkombi" format (e.g. Citreon Berlingo) ... smaller than a SUV with twice the trunk volume (1000l compared to e.g. the 550l of a X3).
I can (and I have) transported four fridge size PA speakers in that car and still have some space on top for monitor speakers. All while still fitting on tight parking places in the city and using 8l / 100km (30mpg?).
Unless you're a contractor/handyman that needs to haul things like drywall, lumber, water heaters, etc. So there are some professions in the city that may require larger vehicles. Also, sometimes those farmer still have to drive into the city for things anyways, like for medical care.
Generally speaking, I believe it is reasonable to only be arguing against the commenter, not the articles or papers they reference.
The commenter in question only mentions SUVs, and not trucks. So even if the article about morality did lump trucks and SUVs in the same category, that's not what the commenter is bringing to the table.
