That's not at all an American exclusive. I live in Europe and everyone parrots the same line when they justify why they're getting a SUV even though they live in the city and never go off-roading.
A work colleagues who just got a baby recently told me he had to get a SUV even though he wanted a sedan because his wife pushed for the SUV with the same argument: "I feel safer in one." What's a guy to do? Do you want to risk for your wife and child to "feel unsafe" because you're too cheap to buy your family a SUV? Same with my cousin, she just got a baby and pushed her husband to get a SUV for the same reason, so I'm definitely seeing a pattern in my circles as well as on the streets.
The estate/station wagon and the mini-van were the traditional vehicle of the family here but now SUVs and the jacked up cross-over abominations are flying off the shelves here. Just look at Volvo's UK line-up[1], it's 8 SUVs and 1 crossover. WTF?!
Justified or not, consumers are noticing this arms race, and manufacturers are more than happy to market and sell you bigger and taller cars for you to "feel safer" in, if you've got the cash.
