What you seem to have done here, is find an article about the dangers of SUVs for collisions involving elderly pedestrians, isolated a single response to it from someone who shares your opinion on psychology, then claimed that it therefore backs up your assertion that the majority only buy SUVs for a feeling of superiority over others as legitimate fact.
I don't really buy that - whilst I completely agree that there is probably quite a large subset of drivers who think driving an SUV gives them some dominance, I don't think its the overriding factor that you say it is. I'm pretty sure my elderly parents with their ageing knees and backs aren't really bothered about dominating the road, nor lording it over others; they just found the ideal car for their needs in the SUV segment. Similarly, I doubt very much that the thousands of young parents ferrying their kids around in cheap Kias/Nissans/Renaults/etc are doing so primarily because they think it gives them some ability to look down on others, but just because again, the raised platform of an SUV is a bit easier to access all the crap you apparently need when you have children. For every idiot I get tailgating me or trying to dominate me in their SUV, there's hundreds of them being driven no differently or more aggressively than any other car.
You obviously have some innate dislike of SUVs, and that's fine - there's plenty of good reasons for that. But attacking the majority owners of them for buying them for nothing other than the psychological boost is nothing more than your subjective opinion. I could quite as easily state that the reason the majority of owners of anything with a BMW/Audi/Merc badge is due to the same, and I'm pretty sure I'd have no trouble finding similar comments online agreeing with me, but I wouldn't try and claim that as a fact as a result.
Are you a peer approved psychologist? If not, then sadly what you think is largely irrelevant.
