Pontiac -
Google and Yahoo maps are good for distance, but I don't think they take into account left turn lights versus right turn "stop, look, and go"s (or do they,
).
I have developed my own routes from experience. Because I am a commuter, I spend a lot of time on the same roads every day. As a result, I have optimized my route. Los Angeles is basically a giant grid of roads. This often gives me "parallel roadway" options that I can take advantage of.
