No kidding, and not being sarcastic:
Since trying this new XE with the SatNav working, I have not been in traffic worse than 2 minutes delay during the past 4 months. And this is NY commuting from Long Island at rush hour.
I did experiment a bit too much with the Nav settings, and programmed the thing to leave me stuck in a 12 minute long traffic pile-up a week ago,.. but I learned my lesson how to readjust that setting.
So I have to say, my current response to traffic has been, turning on the USB music or radio, and following Nav instructions.
