Would You Replace Your Rear Window with a Camera?

The Polestar 4 has arrived on UK roads with a striking design and strong performance. It accelerates from 0–60 mph in 3.2 seconds and notably omits a traditional rear window.

Design and what changed inside

Polestar removed the rear glass to extend the panoramic roof further back. Rear passengers gain extra headroom and a more enclosed, luxury feel.

A roof-mounted camera now feeds a live, high-definition camera feed. The image displays on a digital screen placed where a rear-view mirror normally sits.

Advantages of a camera-based rear view

• The digital mirror delivers a wider, unobstructed field of view than glass.
• Tall passengers, headrests, and luggage no longer block the rear view.
• The system can improve situational awareness in tight traffic and on motorways.

Drawbacks and driver experience

Some drivers report an adjustment period when switching to a screen. Eyes must refocus, causing brief double-vision sensations or perceived lag.

In real-world conditions, lens cleanliness matters. Road grit, rain, and mud can degrade image quality.

Practical concerns for UK roads

Van drivers have long managed without rear glass by using large wing mirrors. Their experience highlights the limits of camera tech when lenses foul.

If the camera becomes obscured, drivers must rely on side mirrors alone. That trade-off worries some commuters and fleet operators.

Family use and interior visibility

Parents used to quick glances at the rear cabin face new compromises. The screen shows only what is behind the car by default.

To see inside the cabin, drivers must switch the display to mirror mode. That action temporarily removes the view of the road behind.

Market response and upcoming choices

Polestar appears to have noted buyer unease. An estate variant of this model is expected in late 2026.

That version is widely tipped to reinstate a traditional rear window. The option will appeal to those reluctant to fully replace rear window sight with camera systems.

As the UK adapts to cars without rear glass, the debate continues. Will drivers trade a pane of glass for a digital mirror and camera feed, or will many prefer the old view?
