I feel like articles like these are red-herrings designed to distract people from the real problem, and/or give them an excuse to feel morally superior when they shouldn't because they drive a normal-sized car instead of a big one.
But here's the real problem: America was a catastrophe of car-dependency even before the bloated SUVs and such started showing up, and merely shrinking the cars back down to normal size isn't gonna fix it. The biggest issue with cars isn't the injuries and deaths from crashes or the or the greenhouse gas emissions; it's the fact that cities are absolutely ruined by trying to build enough parking to accommodate them all. Forcing everything to be spread out in order to fit parking lots and wide roads in between destroys walkability and the viability of transit. The costs of all the extra land -- or even just all the extra concrete for parking decks -- drive up housing prices. Euclidean zoning prohibits convenient access to third places, harming mental health, and even when the zoning does allow e.g. a pub to be built, customers have to drive drunk to get home because it's too far to walk!
My city imposes minimum parking requirements for businesses that want a license to serve alcohol. Not maximums, minimums. Think about how fucking insane and ass-backwards that is for a minute.
The article makes a big deal about how big vehicles are more dangerous to things they crash into than small ones, but consider this: car wrecks kill tens of thousands of people each year, but that harm is dwarfed by the fact that hundreds of millions of people are obese because they're forced to drive everywhere instead of walking. Over 40% of the total US population is obese now, compared to 10% in the 1950s before the effects of car-dependency had a chance to kick in.
The point is, all of these things don't change whether the cars we're dependent on are little hatchbacks or gigantic SUVs. Practically speaking, every car is the same size: one parking space*. It's the parking spaces themselves -- and therefore the cars that occupy them, whether big, small, electric or gas-guzzling -- that have got to go!
(* or one two-second safe following distance when in motion, compared to which the length of the vehicle itself is negligible in terms of its effect on road lane capacity)
