A few weeks ago, I had a three series BMW with two guys trying to screw with my car (getting up on the side real close, cutting me off, slamming on their brakes, etc.) and follow me for a good 10 miles. It was around midnight, and I'm a younger female living in a somewhat rough area. I was genuinely creeped out, and I didn't want them to follow me home. Thankfully, I lost them on a sweeper exit.
I normally get attention from Honda ricers, who end up racing themselves into the sunset. But that was a-whole-nother level of creepy.
