Driving me crazy

Wow, I am out of practice driving in traffic. I find myself really tensing up on these multi-lane roads. It's not congestion or traffic jams, it's just the volume and the way that people drive in an unpredictable way. I don't trust anyone to stay in their lane or to give me any warning of what they're planning to do. I've only been out of the area for a couple years, but I am no longer comfortable with this city driving.
