Age must be the hidden variable here. Saturn, Pontiac, and Mercury were all discontinued (in America) more than ten years ago, and those are the three safest makes.

- clipsy 3y agoIt's possible that age is a hidden variable, certainly, but it's also possible that Saturn, Pontiac, and Mercury are exceptionally low due to selection bias -- as you note, they've all been defunct for a decade at least; this means that every car from those brands still being driven has been in use for at least a decade (presumably longer on average). Since collisions and other accidents (statistically) reduce a car's lifespan, the cars from those brands that are still drivable likely have safer-than-average drivers.
