Here's an entertaining story about being tail conscious;
Many years ago, at a different job, I was driving home one evening after work, when I noticed an older model green SUV a little behind me. It was Fall/Winter, and already dark.
As I continued driving home, I kept an eye on it. I turned left, it turned left, I turned right, it turned right. I watched it follow me through at least 7 turns (which usually means it's not a coincidence).
By that point, I was close to where I was living at the time, but chose to drive past the last turn to my house, to see what the other SUV would do. They made the turn down my street.
So I drove over to the next street, then came down my street from the other end, and I see the SUV parked by the side of the road about 3 houses from mine. As I slowly drive up the road, I can see that their engine is still running, I can just see 2 silhouettes in the dark, but all their vehicle lights are off, and now, alarm bells are going off in my head.
I slowly cruise by, trying to see who's in the vehicle, but it's too dark. I again, choose not to pull into my driveway, and instead, go down to the end of the street and around the corner, turn around, and again, cruise past this SUV, trying to get a look at the occupants, this time, a little closer, as the vehicle is now on my driver's side as I pass it. Still too dark to see.
Turn around again at the end of the street, trying to get a look at the occupants. This time, the SUV's lights come on, and the vehicle pulls a U-turn to come after me. I floor it, take a few quick turns and lose them down one of the streets.
As I make my way back to my street, I turn off my vehicle's lights, and this time, grab the 6 D-cell Maglite I keep shoved in the gap beside the passenger seat. The SUV is back in the same spot on the side of the road, 3 houses down, lights off, engine idling (could see the exhaust fog).
I cruise past again and this time, flick the Maglite on... to see the startled faces of a gal from work, and her BF who worked for the Fire Department.
Talked to her the next day at work and discovered that it was her parent's house. Her BF had picked her up after work, and they were sitting in his SUV chatting (canoodling?) with the lights off, when they noticed
my vehicle cruise past for the 3rd time, which was why HE pulled out after me, to see what that was all about
"Huh. Didn't know YOU lived right there, a few houses down".
