True, lots of places (but I suppose maybe not everywhere) have really wide roads with tons of lanes so it’s easy to drive around with SUV’s, but this is generally not true in Europe where, even in large cities, often roads/lanes are narrower, making SUV’s unwieldy for those driving around them.

Then there’s the pollution aspect which I can’t address, but I imagine SUV’s pollute more on average than other cars (and probably Europe is currently being a bit more stingy on allowing this)
