Solutions for Avoiding Traffic?

gregwbrooks asks: "Technology lets us wardrive and kludge together interesting uses for the OnStar equipment in our vehicles, but what about the one thing I really need: On-demand, real-time traffic information? These guys have a BREW-based app that downloads real-time traffic maps to your cell phone -- it just rolled out in Chicago and Milwaukee, and apparently is going national soon. What other options are out there for someone who doesn't want to fiddle around with tiny web pages on his phone while driving?"
