A close call on the ride home from Sunday brunch with a friend. Something similar happened a few years ago. I guess since the advent of cell phones, people will sit in their cars and talk, text or peruse the internet before getting out. So just because you didn't see a car pull over and park, doesn't mean a door won't open.
I don't remember if there was a car behind me, but there's a good chance I just drifted right.
