I'm guessing I'm a little late to the party on this one, but while driving to a hearing yesterday, I noticed Google maps looked a little different. It now shows which lane you should be getting into.
To be honest, this little change is quiet big for me. I often get frustrated not knowing which lane to be in on the highway when I'm going to unfamiliar places. This takes the guess work out of it. Yet another reason Google maps is the way to go for your navigation needs.
