The Reason Why Are Trucks Getting Bigger

"Bigger trucks pose a greater hazard to pedestrians and smaller vehicles"

It's an arms race.

I used to live near a couple who were both doctors in the ER and they both drive the biggest trucks that they could find because they saw that people in large trucks tended to be fare better in accidents.

I have a small sedan for myself and a smallish SUV for my wife and kids. I feel pressure to upgrade both to something larger.

People don't generally consider that the bigger cars are more likely to be in accidents in the first place even if they come out of it better. Ireland would have much smaller cars than the US but much better traffic record.

So bigger == safer -- isn't giving a nuanced story or understanding. For sure though bigger == less fuel efficient.
