It might have to do with car culture and even urban infrastructure in the US. US is very much a “cars first” nation where a lot of areas do require a car to even get to the closest grocery store, and a lot of people who live in the suburbs like that tend to have bigger cars since it’s perceived as one-part functionality (more space for stuff = less trips to go drive 30+ minutes each way for necessities), one-part status symbol, and one-part fear and/or overcompensating, since a good whack of people here do follow the line of thinking of “if I get into an accident, I’d rather be in the bigger car” despite the fact the chance of killing the other person is greatly increased due to the bad crash collision light trucks have with other cars.

Companies also found a loophole to bypass CAFE laws and can make light trucks cheaper without worrying about safety and emissions too much, so in the US there’s a ton of marketing for comically oversized trucks and SUVs (as a 2m tall person, you can barely see me in some of those cars), with nary a station wagon in sight. Since they have to follow CAFE laws in other countries, I would assume your guys’ trucks are more “normal” and comparable to station wagons and sedans, which also might help with safety.

I've heard roads over there are in average smaller than over here, which if true, might help with that since you would need to be more careful in bugger cars.
