    Moore, Joyce
    2018-06-01 | PDF
    Drivers have poor conceptual understanding of new adaptive driver safety systems (ADAS) such as adaptive cruise control (ACC). When using advanced safety systems, older drivers tend to be more open to learning through reading manuals, but also tend to struggle with learning the uses and limitations of a safety system. Different instructional format ...
