In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Leaf are reminded to check the back seat if they opened the rear door before starting out. The Polestar 2 doesn’t offer a back seat reminder.
The Nissan Leaf has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Polestar 2 doesn’t offer a front passenger side knee airbag.
The Leaf has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. A system to reveal vehicles in the Polestar 2’s blind spot costs extra.
To help make backing out of a parking space safer, the Leaf has standard Rear Cross Traffic Alert, helping the driver avoid collisions. Polestar charges extra for Cross Traffic Alert on the Polestar 2.
Both the Leaf and the Polestar 2 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, lane departure warning systems, rearview cameras, available daytime running lights, around view monitors and driver alert monitors.
The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Nissan Leaf is safer than the Polestar 2:
