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 Sierra EV are reminded to check the back seat if they opened the rear door before starting out. The Cybertruck doesn’t offer a back seat reminder.
The GMC Sierra EV has Daytime Running Lights to help keep it more visible under all conditions. Canadian government studies show that driving with lights during the day reduces accidents by 11% by making vehicles more conspicuous. The Cybertruck doesn’t offer Daytime Running Lights.
To help make backing out of a parking space safer, the Sierra EV’s standard Rear Cross Traffic Alert uses sensors in the rear to alert the driver to vehicles approaching from the side and Rear Cross Traffic Braking automatically engages the brakes to help avoid a collision. The Cybertruck doesn’t offer a rear cross-path warning system.
The Sierra EV has standard OnStar®, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions, remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Cybertruck doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the Sierra EV and the Cybertruck have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, lane departure warning systems, blind spot warning systems, around view monitors and driver alert monitors.
The GMC Sierra EV weighs 1722 to 2336 pounds more than the Tesla Cybertruck. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
