Consumers just prefer larger vehicles here in the US, and those same preferences are also becoming the norm in other countries. You can't blame the modern Camry being gigantic on the Chicken Tax. You can't blame larger vehicles being associated with luxury on efficiency regulations.

Consumers prefer a vehicle that looks like it'll keep them and their family alive on the streets as given - if some other persons kid ends up dead as a result of their choice - well "whateves". Make the streets less dangerous and they might prefer something cheaper and as a side bonus less deadly to their neighbors.

The streets are dangerous precisely because people are in an arms race to have the biggest more "protective" vehicle. Instead regulations would scale that back resulting in safer streets

Seating height doesn't help you see over cars when everybody else is also in a crossover at the same height as you.

But it helps you see car brake lights ahead through the back window of the SUV in front of you

If there wasn't an SUV in front of you this wouldn't be an issue

Cars in the 80s and 90s definitely had more of a "greenhouse" feel to them, with mostly transparent glass and small framing. Due to a mixture of standards, this has changed. The roof cap and pillars have thickened and curved for roll-over protection, and front pillars are also thicker to hold air bags that didn't exist in those older cars. The windows sills are higher up relative to the driver, to improve side-impact…

Cars like the Honda Civic or Volkswagen Golf ha…

This is one of the reasons I daily drive a 1990 BMW 325i—the visibility is just unparalleled.

Even with the increase visibility, I'm sure you'd be much safer in a 2020 BMW 3-series. Heck even a 2010.

A lot of those car manufacturers just don’t care, and it isn’t exclusive to large cars either (though the damage they can do is obviously much higher, making them more dangerous to pedestrians). I like sports cars, so I tried test driving a Camaro about 5 years ago. You would think that visibility on a rather small and fast 2-seater would be at least better than on an average SUV. It was singularly the worst car I’ve…

I got to ride as passenger in someone's new Camaro at about that time, and I fully agree: the visibility was absolutely horrendous. I couldn't believe it. How is such a vehicle legal to drive? Does the US not have any kind of auto regulations governing visibility at all?

Apparently not, considering the topic of TFA

There is another angle here besides the immediate impact (pun intended) of getting hit by a big truck. I'm nearly 60, but I can remember what it was like learning to drive back in 1980. Before SUVs and huge pickup trucks became common, and before tinting windows to near opacity became a thing, it was possible to see road conditions three cars ahead -- you simply looked through the windows of the car or cars in front…

I've noticed this too and this is why I leave at least 5 car lengths in front of me, sometimes even more. I can see around the vehicle in front of me no problem, and can absorb the energy for those rush hour random stops. It seems like 9 out of 10 people follow with less than 3 car lengths, even at 60 to 80mph. This leaves no room for error and anecdotally I've seen it bite people many times.

The 5+ car length strategy has served me extremely well in many years of a 2 hour commute. I can't remember once where I had to panic brake due to being surprised by a random 70mph to 0mph stop, and I can only assume that I'm helping drivers behind me get to their destination safely as well due to absorbing that slinky effect.

The only con is people jump in front of me here and there, but that doesn't bother me one bit.

People way overplay the “everyone will cut in front of you” if you leave five or more spaces - it really will only happen in literal stop-and-go traffic where you are going five miles per hour anyway.

Every single time I see a huge SUV being backed into a spot instead of just parking I think about how dangerous this is. Starting in 2016 all vehicles have backup cameras so that you don't accidentally run someone over. The backup cameras have wide angle lenses. But now you'll have to pull forward with no such camera and a HUGE blind spot.

I've noticed this in the cars I've had over the past 15 years or so too. We hit a deer two years ago because it was moving perfectly in time with the side curtain airbag laden support column in my field of view. I barely saw it when I hit it even! I understand that rillover accidents have lead to these supports being thicker, but why was the solution not to lower the center of gravity on cars so they are less prone t…

FWIW that phenomenon is a geometry thing, not just a fluke. If you are on a collision course with an obstacle at constant speed, than the angle remains constant (as the configuration preserves congruent triangles until impact) and the obstacle can easily remain invisible for a long time, until impact, hiding behind the pillars or even just hidden by the blind spot in your eye if you haven’t moved your head

See https://youtu.be/SYeeTvitvFU for an example.

One of the advantages of raking the front windshield for aerodynamics is changing the geometry for the A pillar to be more sideways instead of vertical, allowing a bit more hope of seeing something.

I rode with a work acquaintance at night once, and noticed he kept his high beams on the whole time, despite oncoming traffic. I eventually said something, like shouldn't you dim your lights when there's someone oncoming? He looked at me like I had antlers growing out of my forehead. "Duh... The high beams are brighter and let me see better." That's the bottom line: Not even a thought about other drivers. And these p…

My 10 years old VW turns off the high beams when it detects incoming traffic, or in general stronger ambient lights (like, street lighting in a locality). But in the US there are no such requirements, I assume.

It’s a feature on new cars, but it’s not enabled by default (you usually have off, auto, high).
