More than fifteen of those cities have challenged my car and me. I grew up in Los Angeles and lived in Brooklyn, Manhattan, Denver and had time spent in Philly, Oklahoma City, San Francisco, Newark and Colorado Springs. The most idiotic set of drivers I've ever seen were Always found in Colorado Springs, CO., but the worst traffic has been in Los Angeles and New York City. Now my home town only has 1/100th of those populations without a single traffic jamb.

This list has been misconstrued. It's about aggression, not how rude or how many vehicles there are. Simply about aggressive driving habits. Changing lanes, cutting people off, speeding etc.

I've driven this country (continental -- not Alaska) many times in my life. I can not count the number of cities (greater than 10,000 or 100,000 or 1,000,000) that I have driven in, most more than once or for a prolonged time. The only states I have not been in are Washington, Oregon, and Idaho. I like driving, but am not naive enough to fully trust the person in other cars. Have I made mistakes, or been in accidents, or gotten mad at the guy cutting in line to turn right or left, or gotten traffic tickets? Yes to all. I try to wave at the car I've made a mistake with -- not always successful. So far, (50 years) I have not caused an accident. When mad, I pretend to shoot an imaginary rocket at the other car; but occasionally I flip them off. I have never had more than 1 traffic ticket a decade -- so far (none this decade). I still love driving -- singing along to whatever song I'm listening to. I've got a fantastic voice when I'm in my car, alone.

Las Vegas is on there, lol! You don't even have to drive in Vegas it's so small! You can uber if you need to get around. This list is kind of lame.

I've driven in about all of them, and I think the list is totally wrong. LA drivers are pretty considerate, the problem is there are just too many of them.

Boston belongs near the top, and it's not even on the list.

Chicago drivers suck too.

I live in L.A. I guess I'm used to it.

I’ve driven in all of them. Can’t say I’ve ever had a problem except for the motorcycles going between rows of cars from San Diego to Los Angeles....that freaked me out at first.

All except Detroit and Austin.
