Actually, yes this last time, but since none of my passengers felt anything, and I just felt a twitch in the steering wheel, and the SUV had backed off by the time I looked in the rear view, I thought I'd imagined it. It was only when we parked at our destination that I saw the mark on my rear bumper, most of which was bumper smudge that wiped off. It's a teensy 1/4" line, down to the black, and I'm waiting for a day when I can leave the car garaged for 24 hours to attempt a self-repair with my paint pens of that and of a small chip on the corner edge of the trunk lid. That is, if I get that confident; I really hate messing with stuff like this, and need to reread all the paint repair advice here on the forum first. To be honest, I don't know that the perpetrator this time was on the phone, but I'm betting.
