It's pretty common and perfectly legal in California that when approaching an intersection, you can use the right portion of the lane if you're turning right, and filter up to the front next to the other traffic in the same lane to do so. That's not exactly the same as traveling side-by-side for a stretch, but it is an example of cars sharing lanes legally.
