status: the car is no longer a "big prestige item" as in previous decades. For millennials and digital natives, there is less focus on ownership of things, especially big-ticket items such as cars. Millennials see cars as "mere appliances—unnecessary, pricey ones that they’ll try to avoid". Legal restrictions; for example, restrictions on teenagers seeking driving licences. Demographic changes; for example, baby boomers drive less as they age, according to one view. Economic factors, particularly unemployment. Saturation of demand in the sense that there has been a "levelling-off" of possible places to travel to by car. According to this view, when road networks were expanding, there were numerous options of new places to drive to, but as road networks have generally stopped expanding, the demand for increased car travel has become saturated. Growth of e-commerce such as tele-shopping, conferences, and smartphone or computer-based social networks. According to this view, these developments have reduced the need for travel by car, such that the "love affair with the phone" has replaced the "love affair with the car" for a proportion of the population, and that widespread use of cell phones and Skype meant there was less need for in-person visits. However, a contrasting view suggested that e-commerce was not a substantial factor explaining less car travel in the United States. Still, countries with higher use of the Internet correlated with fewer 20- to 24-year-olds getting drivers' licenses. One analyst explained about changing attitudes of young people: Another elaborated about the saturation of demand hypothesis: The proposition that car usage has peaked has been disputed regarding vehicle usage in the United Kingdom. In December 2010, Stephen Glaister, the Director of the RAC Foundation, suggested that total traffic has grown more or less as a straight line since the 1950s and such growth will recommence when economic conditions improve; in 2011, the UK Department for Transport predicted a 50% growth in traffic in the coming 25 years. In addition, a corroborating view by Paul Watters suggested that car usage will continue to be important in Britain, and that there won't be “shattering change” by 2020. Scholars studying transport and socio-technical transitions have elaborated possible future scenarios for car use in England and the Netherlands. The advent of autonomous cars is likely to accelerate the decline in car ownership. A recent case study by the OECD International Transport Forum suggested Lisbon could maintain current levels of
