@twiggysays@AlexEdgerton I wouldn't say that. I own a Polestar 4 for a year and a half and driven 40,000 km in it, and I haven't had any problems with it so far.
@chrisramsay52 What you are seeing here is a missile or aircraft exhaust filmed from behind. It looks like this because the exhaust plume at the rear is extremely hot and bright, which causes blooming and sensor artifacts in the image.
