Regarding your post above. I had an Insignia that is probably one of the bigger hatchbacks you can buy. My family fit in a budget SUV, the Tucson much more comfortably than the Insignia and still have the same boot space, if not more, in the Tucson. Also, as mentioned they're a lot easier getting in being 6'4.
And a Skoda Superb has a boot that's about 20% bigger in terms of volume than the Tucson so if large carrying capacity is your NEED then a Superb would be a better option. Depending on the flavour the boot in the Tucson is smaller than that of the Insignia btw. The Superb also has a larger cabin so would no doubt be equally comfortable for the family. Back to the Insignia though the only area I believe it loses out is headroom however try and keep in mind that 6ft4 is waaaaay above average. Not everyone is a freaky giant like you and as I said, and you quoted "few need" them. Not nobody needs them.
For the vast majority of people's needs a standard hatch or saloon is more suitable. But some people want the one thing that SUVs add that you can't get in a standard car, that higher seating position. They will try and excuse it with the 'better visibility' argument but that's highly limited, especially if you read the reviews for the majority of SUVs which tend to share a common complaint of poor rear visibility. It really does boil down to a psychological appeal. It's a bigger vehicle and so provides that sense of superiority. It's the reason that RR's got their nickname of Chelsea Tractors. Many people don't NEED them, I'd argue most, but buy them for the perceived status that they portray.
Hey, if someone wants to try and look like Jonny Big Balls that's fine, but it's when they try and dress it up with disingenuous reasons that it becomes a joke. Seemingly we're a nation of gigantic cripples with 4 obese kids that can't fit in a car from the usual
excuses reasons on here.
