Advanced frontal airbags are not yet marketed because they are not as safe as traditional airbags.

Advanced frontal airbags are designed to enhance safety by adapting their deployment based on the severity of a crash and the size and position of the occupant. Unlike traditional airbags, which deploy with a fixed force, advanced airbags can offer varying levels of protection, making them safer in many situations. They are engineered to work in conjunction with other safety features in the vehicle, such as seat belts and crash sensors.

The reason advanced frontal airbags are not yet more widely marketed isn't due to their lack of safety compared to traditional airbags, but rather related to the costs of new technologies, regulatory approvals, and the time needed for widespread implementation. As these systems become more refined and manufacturers adopt them, advanced airbags are expected to provide an even greater level of safety than their traditional counterparts.
