Do I need 4K or is 2K (1440p) enough for a dash cam?

Across the reviewers we read, 2K/1440p is widely considered the practical sweet spot for license-plate legibility, and several independent sources note that many 'budget 4K' cams use software-enhanced or interpolated sensors rather than true 4K. If plate capture and reliability matter more than spec-sheet bragging rights, a well-tuned 1440p sensor often satisfies.
