I appreciate your perspective. I've spent enough time in other countries now to vouch for your anecdote generally speaking. Though to be honest sizes are increasing in places outside the US as well. It's noticeable on repeat trips over years. Still not as big on average, but it feels like the trend is upward. The gap is not what it used to be. Something like a Corolla Cross or CR-V is taller than what you see in Europe but the footprint really isn't much larger.

Some of it I think is people being actively unreasonable, some of it is larger safety and crumple zones on newer cars, some is the simple fact that the market has shown people like bigger vehicles.

In the end though I guess my point was just that of all the vehicles on the market in the US, it looks to me like the top 25 list is dominated by those in the midrange and smaller categories relative to other vehicles on the market. Whether these are still too large objectively is a topic that can be fairly debated but the fact remains that people are buying things on the smaller end of what is available to them which runs a bit counter to the title of the post.
