Why are the rear cameras lower resolution than the front?

Across nearly every dual-channel model reviewers covered, the rear camera uses a lower-end sensor (often 1080p) than the front. Reviewers note the rear shoots through a second sheet of (sometimes tinted) glass and is mainly there for context and rear-collision evidence, so plate legibility behind you is usually weaker than the front. Buyers who want strong rear plate capture should look specifically at 2K-rear models.
