You are looking at it the wrong way. Driving something so large that it would require a commercial license to transport your family around is ridiculous
They don't require commercial licenses though, because they're not large enough to and don't serve a commercial purpose when transporting families / their things. Plenty of families have the need for third-row seating and the ability to haul things around.
Toyota Camry curb weight is ~3300 pounds. The minivan based on the Camry is the Sienna, curb weight ~4600 lbs. Lincoln Navigator curb weight ~5600 lbs. If the difference between the first two is marginal (~30%), the difference between the second two is less (~20%).
By comparison, actual CDL-requiring commercial trucks weigh up to 80,000 pounds.
Now look at the front end of a toyota sienna vs a lincoln navigator. One slopes down so that you might actually see what is in front of you and allows for pedestrians to impact and roll up and off. The other is effectively a brick notorious for making it difficult to see obstructions in front of you as well as creating an impact that would sooner see the pedestrian explode into a bloody mess over just rolling up and off.
Which has nothing to do with the weight of the vehicle. The Audi SQ8 E-Tron has a sloped hood and weighs more than the Navigator. There are vehicles with a square grille that weigh less than the Sienna.
Time for all of the crossover drivers to admit that they are also part of the problem. They aren't safe just because they are somewhat better than some jacked up bro truck.
That's not the issue. The issue is how tall these grills are and to a lesser extent curb weight. You don't need either to have third row seating or the ability to haul things.
I'd go a step further and say the high hoods reduce utility by making the vehicles harder to work on. I'm 6' and needed a step-stool to change the battery on my uncle's Silverado. The truck manufacturers leave that inconvenient detail out of their macho ads on TV.
I remember when changing spark plugs meant flipping down the front-plate bumper step, taking one step to hop up on the fender, and putting your legs inside of the engine bay while you wrench.
There were adequate engineering solutions for towing even as far back as 2008. The high-hood trend on US passenger trucks is unique to US market vehicles and is factually cosmetic.
Not only do they not need to, they need to actively stop doing that. These are the folks who light brakes & tires on fire, which then spreads to the mountains. There are dozens of spot, brush, and outright wildfires every year from these people.
