It's a fact of life: Nobody ever says the drivers in their hometown are talented and responsible.

No. They're erratic and irresponsible.

But who's got it worst? A new study by fuel-savings app GasBuddy settles the debate over which city has the most aggressive drivers in America.

GasBuddy, whose app has about 70 million downloads, analyzed data from an optional feature that helps users keep track of their driving habits and gives them suggestions on how to preserve fuel.

The analysts assessed the frequency of speeding, hard braking and swift acceleration to gauge aggressiveness.

The study, which examined the 30 largest metropolitan areas by population, concluded these 10 cities have the most aggressive drivers:

1. Los Angeles

2. Philadelphia

3. Sacramento, Calif.

4. Atlanta

5. San Francisco

6. San Diego

7. Orlando, Fla.

8. Detroit

9. Austin, Texas

10. Las Vegas

It's no wonder that the City of Angels is No. 1, since LA's drivers are far from angelic.
