It's also decreased for anyone NOT willing to buy a "light truck" (e.g. a modern SUV). There's a loophole that makes it so that light trucks don't have to be tested against the same safety standards as other vehicles. Basically they just have to prove they're safe to crash into other light trucks but do not have to be tested against regular passenger vehicles. This loophole is credited as one of the main reasons car fatalities have been rapidly growing in the US but falling in most other nations. And also for the massive recent explosion in size (again, mainly observed in the US).

But size is just one factor that's reduced safety. Another one is reduced visibility. One of the contributors to the rise in fatalities has been due to parents literally running over their own children in their driveways. These are low-speed, suburban vehicle fatalities that are not happening in other countries
