For me this is not a problem. I glance at the top left of the screen to see the direction of the next turn, left or right, then I get in the left or right lane. Also, when I miss a turn the rerouting is fast enough it's hardly a problem.
My big complaint is that Google maps announces I'm on the fastest route even when I know I'm not!
