Hasn't this caused an arms race of sorts where these trucks get bigger and bigger to the point where now some models have worse visibility than enormous M1 Abrams tanks: https://carbuzz.com/news/the-abrams-m1-tank-has-better-visib...

It's definitely one of the reasons cars in general have gotten bigger, you can't deny that better survivability in crashes is good marketing material. Trucks are just among the larger of them.

Yes, but it's only better survivability in two-car crashes, and it makes the overall survivability worse. The social cost is greater than the private benefit.

IOW, it's a market failure (externality).

It's this exact line of thinking that explains why there's an arms race going on - not just in larger vehicles, but a literal one where carrying a gun makes one person safer but almost everybody else around them less safe.

I don't remember the exact stats, but something like 30-50% of lethal crashes happen alone, without another vehicle involved, because drivers lose control of a vehicle.

If you hit a bridge pillar or drive off a cliff, it doesn't matter how heavy your vehicle is.

I'd for these types of crashes it's much better to have a small, nimble vehicle that is more stable and doesn't crash in the first place rather than a huge truck with poor grip that tips over if you corner too fast.

Well, unless you hit another F350.
