I have a Polestar 2 as my daily driver. It's fun to drive, good handling, nice infotainment, and decent lane assist. The lane assist is better than my Audi E-tron SUV or my Taycan but not as good as Tesla. It does not automatically change lanes, but pauses the lane assist when you turn on a blinker and then re-engages when the blinker is turned off. It will go around moderate curves in the highway and doesn't ping-pong like the Audi or Porsche. It's also really good at low speed stop and go traffic, and easier to turn on and off compared to the Germans.
Overall it's a great car. It does feel more cockpit like (which I prefer) compared to a Tesla or an Ioniq 5, but it does have the hatch which is better than a Model 3, and it's way more sporty than an Ioniq 5. Charging speed and range are the biggest drawbacks in my opinion, but I won't be using mine for long road trips.
The biggest selling point for me were the Polestar lease rates. They are very competitive against any of the other EV's in the same price range. Cheaper than a similarly equipped Model 3/Y, Mach-E, or Ioniq 5. My lease is 3 years, 10k miles, fully loaded at about $600 a month with 3 years of free Electrify America charging.
