Open Source Driving Directions?

Even back when I used it regularly, I disliked MapQuest. After a couple of “get on the tollway, exit, then get back on the tollway” directions, you start to second guess everything from them.

Up until yesterday, I was extremely pleased with maps.google.com. Then the big G got me lost. Sure, to google’s credit, it was an unclear intersection. Sitting at the stoplight, I wasn’t sure if I should go straight or, as the directions suggested, turn right. Should have gone straight.

Makes me wonder, is there an open source driving (and walking) directions site?

Something update-able by the people familiar with the roads and destinations. With Google’s Map API, it’s theoretically possible to re-do their directions.
