Something rather obvious is missing in the Precept, and it took us a moment to realize it: there’s no rear window. Instead, the rear-view “mirror” will be a display that uses video from a rear-facing camera. Given how useless as some modern car and crossover rear windows are, this seems perfectly logical, and many manufacturers (like Cadillac) boast displays that can alternate between a rear camera view and a traditional mirror. It appears that this will be heading to production if Polestar’s body-in-white is any indication. Let’s hope there’s at least a washer built in, because if that camera gets obscured by ice, dirt, grime, or salt it becomes pretty useless.
