Following for miles

Yes it is annoying to me. I drive nights and not that it’s scary but it does seem suspicious, I start thinking is he drunk, overloaded, lost, hypermiler, sunday driver, too old to drive, too tired etc. have to keep checking the mirror more often rhan I usually would. It’s like I got something stuck between my teeth. On a few occasions I’ve let off the acc. to drop down to 45 to make them pass me. I just don’t like it. I mean you prob. wouldn’t like it if someone was following you on the street walking behind you for miles, right. Even if it’s just a coincidence and they’re going the same way as you
