This work package developed a range of future scenarios with varying degrees of green driver support, considering technological, human and political perspectives. These scenarios will be used in the microsimulation (WP53) and the scaling-up (WP54). Focus groups and a survey were carried out, as well as aggregation to the vehicle market. In the focus group discussions, eco-driving systems were valued for heavy vehicle, fleet markets and individual drivers, with commercial buyers sensitive to costs and HMI, but private buyers concerned with engine type and fuel economy – both relating to costs. In the survey, purchasers indicated that they were willing to pay substantially more for a built in advice system as compared with a mobile phone app.
