I’m certainly no expert in the matter, it’s just that these seem well designed in general, and they obviously didn’t shy away from design choices out of fear of looking stupid, so they must have conside tred a flat front and decided against it for some decent reason.

One other one that comes to mind, now that I’m thinking on it again: if you do hit a pedestrian or cyclist, they’re likely to go under a flat-fronted vehicle, but end up on the hood of a vehicle with a low hood
