Yup, Polestar is pretty good with OTA updates as well. Most excellent, some not so much. The car has changed considerably since we've bought it. The one thing I don't like is how the Automatic Cruise Control has been reprogrammed to make it more 'efficient', but it is a material change with no options for different maps and now I find it is too slow in picking up speed, but more annoyingly it has got a greater over and under run. Well outside the 10% of the set speed at times, very annoying.Generally as I am aware, most modern cars are capable of getting software updates. How they get those software updates is another matter. Some have to be plugged into specialized equipment. Others get over-the-air updates. My last car, had a wifi hotspot and was capable of getting over the air updates. In that time of ownership, I may have had 2 "system" updates and 2 map updates. I don't think the system updates affected more than the infotainment functions.
Tesla sends out updates every few weeks. Some of them are jaw dropping, like increasing range with a software update. Rivian from what I understand also does a good job with software updates. And other BEV manufacturers are trying to get on board with regular software updates.
Besides the car itself, Google has updated the maps considerably as well since we got it. It was fine originally, the routing worked well, the traffic was great, the charging points and preconditioning was good enough. But over time we got better filtering of chargers, live status regarding availability and service, satellite maps, awareness that there is a charger at home (or not), and now also at a destination (or not). Different routing algorithms not just based around charging but also efficiency, super details 3D, integration with desktop google maps, and so on. It's constantly updating.
