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 EQE Sedan 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.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The EQE Sedan has Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The Polestar 2 doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.
Both the EQE Sedan and the Polestar 2 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, front seat center airbag, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, around view monitors, rear cross-path warning and driver alert monitors.
The Mercedes EQE Sedan weighs 566 to 1030 pounds more than the Polestar 2. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
