Works in Germany where they have good road manners. The US is too full of ass wipes to do it. It will always end with someone doing 30+ mph faster in the ending lane and then diving into the open lane. Usually without a blinker. I tend to use the closing lane til I hit the 500ft mark and then merge. Then, even as a BMW driver, I use my SIGNAL. I think that's a bigger problem that needs to be taught to kids in school now. Use your FUCKING SIGNALS.
