I'm actually really glad you used that word - "tank". Because as that video and website illustrate... Some of the SUVs people are driving now are often comparable in size to the biggest of WWIIs tanks, albeit minus the gun mount. It's just completely unnecessary and excessive for most of the people driving them around now.
At some point, this "I can do what I want with my money" mentality starts making things worse, and more dangerous, for everyone else, and imo that's when you become a bit of an arse for making selfish choices. Not only are you influencing the market so the rest of us don't have as many sensible options, but you are putting your own and others' lives at greater risk with that choice. That cost-benefit only becomes even remotely rational in a very specific set of circumstances, which I think some people obviously do meet. But there's also a lot of whataboutery from people who could get by comfortably with alternatives if they really wanted to, they just don't want to. Which, again - "I can do what I want with my money" shouldn't fly when you start endangering other people for your own vanity.
But then you know, as that video also raises, in at least one instance industry research results essentially boiled down to showing that SUV buyers were significantly more likely to display a whole selection of traits that essentially amounted to being selfish in general and dangerous in their driving habits, and in the vast majority of cases used the features SUV ownership is "justified" with once a year or less (towing, going offroad). Features which smaller, different models or cars are often perfectly capable of covering anyway.
Honestly - the video says it all excellently with a wealth of sources.
