Compared to other popular modes of passenger transportation, the car has a relatively high cost per person-distance traveled. The income elasticity for cars ranges from very elastic in poor countries, to inelastic in rich nations. 〔 〕 The advantages of car usage include on-demand and door-to-door travel, and are not easily substituted by cheaper alternative modes of transport, with the present level and type of auto specific infrastructure in the countries with high auto usage. Public costs related to the car are several including congestion and effects related to emissions. ==Private benefits== The benefits of using a car differ by many factors, in regard to location and culture. One general benefit is availability of use which, when coupled with public support via infrastructure (such as roads or fuel stations), can allow highly flexible movement and transportation. Because public transportations are not as well omnipresent and normally don't run at certain day periods, they might not be an option. Car allows a certain freedom of movement, that other means of transport do not. Another private benefit car owners pay, is comfort. The car allows the transportation of the driver (and passengers) from a certain point A, to another point B, within an acclimatized and protected interior. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Economics of car use」の詳細全文を読む スポンサード リンク
