"Weird" is definitely subjective when it comes to car design! The Polestar 4 is certainly… distinctive?
The most talked about thing is probably the lack of a traditional rear window. Instead they've got a high-definition screen that displays images from a rear-facing camera. Some people find this innovative and futuristic, while others think it looks odd and might affect visibility. There's also the overall styling, which is very minimalist and Scandinavian. Some love it, others find it a bit too much. Ultimately, it comes down to personal taste. What one person considers "weird," another might see as bold and refreshing.
Have you seen it in person yet? Photos don't always do a car justice. I'd love to see one myself and judge.
