Self-driving vehicles will lead to a rise in car sex, according to a new study.

People will be more likely to eat, sleep and engage in on-the-road hanky-panky when robot cars become the new normal, according to research published in the most recent issue of the journal Annals of Tourism Research.

“People will be sleeping in their vehicles, which has implications for roadside hotels. And people may be eating in vehicles that function as restaurant pods,” Scott Cohen, who led the study, told Fast Company magazine.
