Cars nowadays are larger for improved comfort, not because of safety features. Larger cars aren't inherently safer. Modern safety features, such as airbags, crumple zones, etc., have been around for over twenty years now, but cars have gotten larger.
Regardless, the comparison was between Kei trucks and pickup trucks.
Cars are in fact larger partially due to advanced safety features, in particular doors, pillars etc. have gotten a lot thicker over the last 25 years.
> Larger cars aren't inherently safer.
Yes they are, you're probably better off in a crash without a seatbelt in a bus than in the highly safety rated mini the bus crashes into. Newton matters.
> Cars are in fact larger partially due to advanced safety features, in particular doors, pillars etc. have gotten a lot thicker over the last 25 years.
I would like to see a citation on this. Car doors have gotten larger partly because there is so much more stuff going on there than 20-30 years ago, mostly a bunch of new electronics. They are also larger because, well, the cars are larger.
> ... you're probably better off in a crash without a seatbelt in a bus than in the highly safety rated mini the bus crashes into.
This is obviously not a fair comparison. I would be safer in a tank as well. Fact is, a current generation Toyota Camry is effectively safer than an early 2000s F-150.
E.g. [1] has a decent overview of the side impact saga for the Euro NCAP since 1997. I'm less familiar with how the American version has kept up.
In any case most mass market American cars target the Euro NCAP's safety tests, so it affects car design across the pond too.
> [...]mostly a bunch of new electronics.
I can't think of any electronics in doors than weren't there in 1995.
Powered windows have gotten more common, but if it weren't for safety considerations the thickness of doors should have reduced since then, as all the electronics involved are smaller now.
> Fact is, a current generation Toyota Camry is effectively safer than an early 2000s F-150.
Probably, but some quick internet searching reveals that if you add the weight of one person to the modern Camry it's probably heavier than the 2000s F-150, or thereabouts.
What I was referring to is that crash safety tests don't account for crashes between differently sized vehicles.
That's probably intentional, as regulators don't want to cause an arms race towards ever bigger cars.
> I can't think of any electronics in doors than weren't there in 1995.
Electronic locks, speakers, electronic bits of heated mirrors, airbags, etc. were absolutely not that common in the average 90s car.
Also, car dimensions are generally larger because we ourselves have become larger and taller. This becomes exceedingly obvious when comparing European cars in the past 40 years. If we look at the last 15 years, the trend is to make larger, more spacious cars, to the point where most firms are betting on SUVs over sedans.
> What I was referring to is that crash safety tests don't account for crashes between differently sized vehicles.
They do, though. What would be the point of testing a car safety measures only against cars of its size? In fact, there are plenty of videos out there of crash tests between sedans and trucks.
> That's probably intentional, as regulators don't want to cause an arms race towards ever bigger cars.
Uh? Manufacturers have been steadily increasing the size of cars in the past 20 years. Each Camry generation is larger than the previous one, and has nothing to do with regulators, it’s just that buyers want spacious cars.
If you wanted to make a car with the same outside dimensions today you could barely cram two people in it, due to all the mandatory crumple zones etc.
Of course consumer demand is also part of it, but in some cases car manufacturers are still making 1980s design cars today (e.g. the 79 series Toyota land cruiser), they're just outlawed in Europe due to safety, pollution etc. regulations.

I'm talking about official safety ratings, e.g. this in the Euro NCAP:
Although as that page explains the particular bias I had in mind was "fixed" in 2020, now it's a 1400 kg mobile trolley, so heavier cars are tested somewhat more realistically.
Regardless, the comparison was between Kei trucks and pickup trucks.
