It's not commonality, it's that even if like for like the vehicles are equivalent or even safer there's selection bias at play as a result of what they sell and who they sell it to. To use a very broad brush:

People who buy Tesla sedans are basically the "german car weaving with no blinker" demographics of yesteryear so if someone's gonna hit a pole at 100 it'll be them.

Buick sells pretty safe stuff to pretty conservative buyers buy they skew toward age where they'd keel over from an open hand slap so surviving more than a fender bender isn't likely and they're exactly the kind of people who are gonna get t-boned at 60 by something they just didn't see.

Dodge basically sells Challengers and Chargers these days (Ram is separate brand for the timeline listed) and the stereotype seems to generally check out.

Hyundai and Kia are kind of the odd ones out but they sell a lot of low end and small stuff which doesn't exactly attract the least risky buyer demographics and the cars aren't exactly loaded with safety themselves.

The comparison really needs to be done on a higher resolution otherwise you get stuff like Volvo and Lexus looking artificially good because of course nobody dies in high end SUVs and sedans driven mostly by people of non-risky age and decent means and Ford and GM look good because they sell god knows how many fleet vehicles that only get driven responsibly on the clock and it's kind of hard to kill yourself in a 3/4 ton pickup anyway.
