What are the advantages of using a car service instead of driving yourself?

1.  The primary advantage of using a car service is convenience.   You can arrange for your vehicle to be picked up and dropped off at any time, day or night, without having to worry about parking or finding a ride home.
2.  Another major benefit of using a car service is safety.   Driving in unfamiliar areas late at night or early in the morning can be dangerous.   Having someone else drive you home ensures that you arrive safely at your destination.
