Cars extended the range of dating as well as enabled back-seat sexual exploration.

Dating is a stage of romantic and/or sexual relationships in humans whereby two or more people meet socially, possibly as friends or with the aim of each assessing the other's suitability as a partner in a more committed intimate relationship or marriage.

It can be a form of courtship consisting of social activities done by the couple.

Dating as an institution is a relatively recent phenomenon which has mainly emerged in the last few centuries.
