A car that can operate in a fully automatic way may cut the weekly cost of fueling up. Whether fuel is provided free by third parties or come directly out of pocket, driverless cars may lower strain on energy infrastructure. A key feature that allows this is the cruise control nature of the vehicles. A driverless car is essentially a car that is more often on cruise control. This could lead to a better use of resources in operating vehicles and, at the end of the day, save each of us more money.
