First off, consider that Google Navigation Beta comes free on all Android phones inside of the Maps app... And it's an exquisite navigation program and is already integrated with the Car Mode app thingie and all. Do you see yours being that much better that user's will see a reason to switch from the standard, free, kickass Google app to your paid app? Sorry, I don't mean to burst your bubble, just trying to be realistic.
Now, if you still wish to continue: OpenStreetMaps and GoogleMaps try their best to know traffic rules--basically they know as many rules as have been programmed into them on their GIS layers thus far. I have certainly had experiences with Google Maps where it has told me to make a left or right onto a one-way street going the opposite direction. Gotta thank my brain for catching those mistakes early enough!! Basically, all these mapping softwares have disclaimers taking away any blame for inaccurate map data. Both street map systems are capable of routing a path only on drivable paths (ie, roads).. If you dig around the Google Maps Android API docs [over at code.google.com], I believe I've seen some methods in there for getting driving routes. I doubt Navigation tutorials exist, but there are loads of Google Maps intro tutorials. Google "android maps api tutorial" or something.
