Polestar’s system name Pilot Assist accurately portrays system functionality. The promotional material and the handbook correctly indicate the limitations of the system capabilities. Status information is clear but the Polestar does not offer a head-up display showing the system status in the driver’s direct line of sight. Polestar did not equip the vehicle with an internal camera and relies only on steering wheel input for Driver Monitoring. The system balances driver steering input with lane guidance, promoting co-operative driving.

Polestar combines map-based speed limit information with real time camera inputs to manage fixed, variable and temporary speed limit signs. The system cannot adapt speed for upcoming road features such as curves and junctions. The Polestar 2 avoids a collision with moving vehicles in the ACC test scenarios but fails to respond to stopped cars. AEB interventions provide limited additional support in critical situations. Polestar upgraded the steering support offered by the Polestar 2 in late 2021. Now, the driver is supported through the S-Bend and stays centred in the lane at all but the lowest test speed. The vehicle has an Active Blindspot system designed to prevent lane changing into adjacent vehicles. A lane-change assist function is not available. In case of an unresponsive driver, the Polestar performs a controlled stop in lane. If the radar or camera are blocked the car provides a timely warning and prevents system activation.

The Polestar 2 provides a moderate level of Vehicle Assistance with a good level of Driver Engagement and a good Safety Back-up resulting in a Good and balanced system.
