I've just read on the google blog about a new project called Google Transit. It's a nice little feature that allows you to get local transit schedules and routes (displayed on google maps - go AJAX go! ;-) ) via a simple search engine like free text query. Cool. But even cooler: they include the price for the trip and compare it to the price of driving the same route by car. Cars lose again.
Here's an example query:
