text: Driverless cars could be possibly more efficient than current cars. For example, a driverless car with a GPS could possibly find the quickest and most fuel-efficient route to a destination. Another thing driverless cars may be able to do more efficiently is determine the best way to save gas or prevent wear and tear to the car on a case by case basis. For example, a car with a smart computer may be able to decide whether it is more fuel efficient to turn off the engine or leave it running, depending on the amount of time it will be left idle. To combat wear and tear, a driverless car may be able to accurately determine the best distance and amount of time to brake to keep the damage to tires and brakes as low as possible.
