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 Optiq are reminded to check the back seat if they opened the rear door before starting out. The Model Y doesn’t offer a back seat reminder.
The Optiq has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Model Y doesn’t offer front seat center airbags.
The Optiq’s standard pretensioning seatbelts also sense rear collisions and remove slack from the seatbelts to help protect the occupants from whiplash and other injuries. The Model Y doesn’t offer a whiplash protection system.
To provide maximum traction and stability on all roads, Full-Time Four-Wheel Drive is standard on the Optiq. But it costs extra on the Model Y.
The Optiq has a standard HD Surround Vision to allow the driver to see objects all around the vehicle on a screen. The Model Y only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
To help make backing out of a parking space safer, the Optiq’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 Model Y doesn’t offer a rear cross-path warning system.
The Optiq’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Model Y doesn’t offer a driver alert monitor.
The Optiq 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 Model Y 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 Optiq and the Model Y have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, 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, daytime running lights, lane departure warning systems, blind spot warning systems and rearview cameras.
The Cadillac Optiq weighs 794 to 829 pounds more than the Tesla Model Y. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
