For people with disabilities it is much easier to get into and out of an SUV than a regular car
Nice... That's an extremely low percentage of people. And that still depends on the disability the person in question has which makes it an even lesser percentage overall.
Yet like half the cars if not more now, I see on the streets are SUVs.
and the high roofline and larger boot mean it's easier to fit mobility aids inside - although the higher boot floor often means heavy/large equipment such as powered wheelchairs needs lifting compared to an estate car (or a hatchback, though many have quite high boot lips)
So... not really much of an advantage really in this practicality aspect.
SUVs also have typically better towing performance than estate equivalents. Those who tow - particularly if they are novices - are commonly advised to not tow a trailer in excess of 85% of the towing car's kerbweight (to avoid trailer-led situations), which means SUVs are more suited due to their higher kerbweights. That's not a legal requirement though.
Another very low-percentage of people. This however I can agree with the larger weight (and thus torque) of the SUV will help with that.
But again, a very niche thing which doesn't explain the vast amount of SUV sales.
That aside, the argument of what you really need from a car rapidly descends to the inevitable conclusion that nobody needs a car that sounds nice, goes quickly, has a manual gearbox, looks nice, has a nice interior, and we should all just have whatever the most basic car available is because nobody needs anything more than that.
This is, of course, not how it works. We buy cars according to what we want from a car, and if someone wants a car that's a bit taller for whatever reason is important to them it's no less valid a choice than someone else wanting a V8 because noise. Or indeed both a V8 and a car that's a bit taller, since that's also an option.
It really depends on what kind of SUVs we talk about really.
For example, is the Nissan Terrano I and II or the old Mitsubishi Pajero considered SUVs? Because if so, those are actually useful SUVs for being a daily. Those can actually off-road.
When I talk about pointless SUVs I mainly refer to things like literally any "supercar" SUV (Urus, Purosangue), because these are just show offs. You want an exclusive show-off car that can actually perform, buy an actual supercar. And not a fat SUV.
And then you have the more common Qashqai, Tucson, CR-V, CX-5 and the like.
And those SUV coupé monstrosities.
These are no better than their wagon / estate / minivan variants, especially not when it comes to fuel consumption, safety, driveability...
And then there's the "people" problem. Majority doesn't even take into account the actual needs when buying a car anymore and just resort to superficial things like "I want it tall, or I want it to look nice, or I want it because it's the trend".
Heck, there's posts all over the internet with objective reasons of why SUVs are not a good car category in the grand scheme of things.
EDIT: LOL just type "Why SUVs s*ck" on google and even wikipedia has an article on it (and one with very good reasons at that btw).
For every argument for SUVs, there's 10 against it... (figure of speech in case this gets misunderstood).
