The ID.BUZZ’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Optiq doesn’t offer pre-crash pretensioners.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The ID.BUZZ has Car2X, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The Optiq doesn’t offer a system that can receive automated systems
The ID.BUZZ Pro S Plus has a standard Overhead View Camera to allow the driver to see objects all around the vehicle on a screen. The Optiq 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.
The ID.BUZZ has standard Car-Net, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in or send emergency personnel to the scene if any airbags deploy. The Optiq doesn’t offer a GPS response system, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the ID.BUZZ and the Optiq have standard driver and passenger frontal airbags, 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, rearview cameras and rear cross-path warning.
The Volkswagen ID.BUZZ weighs 796 to 1005 pounds more than the Cadillac Optiq. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
