This is a great tool....still needs to expand the cities and metro services... I'm sure its on the way.....Google will make a good return if ads ran on the sides when people used the site. I suggest adding a telephone side to it. People should be able to call Goog 411, say "Transit Trip Planner" and be routed to a talking system that can lookup bus times, give directions, etc. Sometimes, you're in an area where Wi-Fi cannot connect but you can get phone coverage. Other times, you only have phone, as per not having a paid net ability on your device.

I think this would be great for Students and Business People, who each travel and may not always have a car, etc....
