> That tells me the car shouldn't be labeled as a killing machine since the road design bears the responsibility in this perspective.
I hear you. This is why most mature traffic safety and transit advocacy is about encouraging infrastructure changes, encouraging even traffic enforcement, and trying to add sensible legislation around vehicular responsibility (like alcohol rules and the like).
The problem is, car culture is a thing that exists in America (and many parts of the world of course), and that culture often actively embraces reckless acts like speeding, unsafe hauling, coal-rolling, or unsafe vehicle lifting. Car culture also often actively pushes back against efforts to make the roads safer like automated traffic enforcement or stricter licensing requirements, and leads to negative things like catcalling from cars. You don't have to take my word for it, just check out https://reddit.com/r/cars and look at the jokes and memes they say. I'm also willing to bet that the average subscriber of r/cars is a _safer_ driver than the average American driver because of their enthusiasm.

In theory. In practice, the numbers show that these safety features aren't enough.
