Traffic is the one of the most relative things out there and the comparison will be different for nearly everyone. If you currently live in a somewhat more rural area or small town with limited traffic, it can certainly seem nuts. In the 10 years before I moved to Orlando I lived in Ft Lauderdale and Dallas, so Orlando traffic is occasionally annoying and that's the extent of it. Most of the time, I just don't find it that big of a deal; It's all about the baseline you're comparing it to though.
That however, is a very good example of what I was referring to in the earlier post about getting a feel for the neighborhoods you might be considering before making a decision. If your threshold of pain for traffic is very low, there are lots of of the Orlando metro area you should avoid.
