The new version of Google Maps for Mobile (2.2) is offering public transportation directions "in all of the same places as the web version of Google Maps, including Chicago, the San Francisco Bay Area, Seattle, Vancouver, and over 40 other cities in North America." Users will also be able to easily browse through all scheduled trips and get information on the last transit trips for the day. Throw that in with the "My Location" feature, and you have yourself a useful tool in the fight against high gas prices.
I gotta love Google Maps on my BB Curve. Saved me a few times in Hawaii last week! I wonder if they will have tram and monorail info for my beloved home Vegas? walk 2 blocks from Excalibur, walk .3 miles towards luxor towards giant light, avoid begging bum, watchout for porn peddlers, buy yard sized plastic frozen margarita, get on tram to Bellagio, puke on small child, scream "VEGAS", miss plane .8 miles :)
