RBI #2: Public Transport Directions on Google/Yahoo Maps

Here is Random Business Idea #2

I realize we're living in a driving nation – with crude oil breaking $70/barrel, perhaps we should pause to rethink?  It doesn't help that we have one of the worst public transportation system amongst all developed nations.  But I digress…  Let's focus on more manageable topics. 

As a first step, how about including public transportation options on digital maps?  Being a New Yorker, knowing how to get from Soho to UWS by car is really of little use – I don't own a car, and even if I do, I won't attempt the impossible.  How about a simple subway/bus map overlay?  Or better yet, interactive directions for transport within and beyond major cities – I suspect I'm not the only one who'd find this service tremendously useful.  More so than satellite maps. 

Update: My friend, Ingrid, made a great suggestion in comments.  Thought it's worthy of a quote:

"On a related note, these driving directions are perhaps more relevant when you're on the road – I can attest to the pressing need recently when returning from Vermont. A last minute change of plan led to 'uncharted territory', and an idea dawned one me: Wouldn't it be a great service for Verizon to set up some public internet booths at highway sevice areas or rural gas stations? That is, as public utilities, not unlike the ubiquitous public/pay phones. The utilitarian dimension of the internet remains to be tapped."

I absolutely agree!
