A bullet train between L.A. and San Francisco that would eliminate the maddening routine at airports and save pollution and tons of fuel? Don’t hold your breath — this L.A. Times story says there are tons of problems with the way the plan is going forward, chief among them leaving Sacramento and San Diego off the “first phase” (read: before the year 2020) of construction.

Transbay AC Transit buses got wi-fi service beginning last Wednesday. And speaking of wifi, remember that CalTrain did a “successful proof of concept” last year? That doesn’t mean it’s up and running. They don’t expect wifi on CalTrain until the end of 2007.

But ACE, the Stockton-to-San Jose commuter line? They got wifi, if you ride the first car.
